ISB Letter of Recommendation (LoR): A Comprehensive Guide

By admitStreet Team

Letters of Recommendation (LORs) are a critical aspect of your ISB PGP application. They offer a unique, third-party perspective on your professional abilities, leadership potential, and character. 

Since ISB emphasizes peer and supervisor feedback to gauge your readiness for the MBA program, selecting the right recommender and guiding them effectively can significantly impact your application. 

In this article, we’ll cover everything you need to know about ISB LORs, including expert tips, how and when to choose a recommender, and sample recommendations for each question.

How and When to Choose a Recommender for ISB PGP

Choosing the right recommender is critical to the success of your ISB application. A well-chosen recommender can provide insights into your professional skills, leadership potential, and personal growth, all of which are essential for a strong Letter of Recommendation. 

Here’s a guide on how and when to make this important decision:

When to Choose a Recommender

It’s never too early to start thinking about who will write your recommendation letters. Ideally, you should start this process at least two to three months before your application deadline. This will give you sufficient time to identify potential recommenders, reach out to them, and ensure they have ample time to write a thoughtful and detailed recommendation. 

Early preparation is key to avoiding last-minute requests, which could lead to rushed or generic letters.

  • Three Months Before Deadline: Begin identifying possible recommenders and approach them informally. Gauge their willingness and availability.
  • Two Months Before Deadline: Finalize your recommender(s) and provide them with background information, including your resume, application goals, and key achievements.
  • One Month Before Deadline: Follow up and check if your recommender needs any additional information or clarification to complete their letter.

How to Choose a Recommender

When choosing a recommender for your ISB application, it’s crucial to select someone who knows your professional abilities well and can provide specific, detailed insights into your achievements and growth. 

Ideally, this person should be your current or former supervisor, as they can speak to your work ethic, leadership skills, and contributions to the organization. If your current supervisor is not an option, consider a senior colleague, client, or project leader who has worked closely with you on key initiatives. 

Avoid selecting someone based solely on their title, as a well-written, personalized recommendation from someone who has directly observed your performance will carry far more weight than a generic letter from a high-ranking executive. 

Make sure your recommender understands your career goals and how an MBA fits into your overall plan, as this will help them write a more aligned and impactful letter.

Expert Tips on Crafting Strong Letters of Recommendation for ISB

Your Letters of Recommendation (LoRs) can have a significant impact on your ISB application by providing a third-party perspective on your professional skills, leadership potential, and personal growth. 

Here are expert tips to ensure your LoRs make a powerful case for your candidacy:

1. Choose Recommenders Who Know You Well

The strength of a recommendation lies in how well your recommender can speak to your professional journey and personal attributes. Select individuals who have worked closely with you and can provide specific examples of your achievements, leadership qualities, and growth. Your current supervisor is often the best choice, but if that’s not feasible, a former supervisor or client who has a strong understanding of your work is a great option.

Tip: Avoid selecting recommenders based solely on their titles. A detailed, personal account from someone who knows you well is far more valuable than a generic letter from a senior executive with little knowledge of your work.

2. Provide Your Recommender with Context and Guidance

Once you’ve chosen your recommenders, make sure they have all the necessary information about your career goals, key achievements, and reasons for applying to ISB. While you shouldn’t write the recommendation for them, you can share your resume, discuss the ISB application requirements, and suggest examples of your work that they can highlight.

Tip: A well-informed recommender will be able to tailor their letter to emphasize the qualities ISB values, such as leadership potential, problem-solving skills, and the ability to thrive in a collaborative environment.

3. Emphasize Specific, Measurable Achievements

Strong recommendations include specific, measurable examples that showcase your skills and impact. Encourage your recommender to highlight tangible achievements such as leading a successful project, generating significant business results, or mentoring team members. These examples lend credibility to their assessment of your strengths.

Tip: A recommendation letter that states you are “a great leader” is less impactful than one that says, “They led a cross-functional team of 10 people to achieve a 25% increase in efficiency within six months.”

4. Highlight Your Leadership and Growth

ISB values candidates with leadership potential and the ability to grow from feedback. Your recommender should provide examples of how you’ve demonstrated leadership, either by managing teams, spearheading initiatives, or taking ownership of complex challenges. Additionally, the letter should mention how you’ve responded to constructive feedback and how that has contributed to your professional development.

Tip: Ask your recommender to mention instances where you took initiative, whether it was during a project or in helping others within the team.

5. Address Your Unique Qualities

Ask your recommender to highlight any qualities that set you apart from others. These can include your problem-solving skills, ability to work under pressure, creativity, or interpersonal skills. It’s also important for the recommender to compare you with peers in similar roles and demonstrate why you stand out.

Tip: Encourage your recommender to discuss both your technical and soft skills. A balanced assessment of your abilities will paint a fuller picture of your potential as an MBA candidate.

6. Ensure Consistency with Your Application

Your LoRs should complement the rest of your ISB application. Work with your recommender to ensure that the examples they provide align with the experiences and achievements you’ve highlighted in your essays and resume. Consistency across these elements creates a more cohesive narrative and reinforces your strengths.

Tip: Share your essays or application goals with your recommender, so they can write a letter that aligns with your overall story.

7. Give Your Recommender Ample Time

Writing a thoughtful and well-crafted recommendation takes time. Approach your recommenders at least two to three months before the application deadline, allowing them sufficient time to prepare the letter without feeling rushed. Follow up with gentle reminders, but be respectful of their time.

Tip: Offering to have a discussion with your recommender about your goals and achievements can help them write a more personalized and impactful letter.

8. Keep the Tone Professional Yet Personal

A great recommendation strikes the right balance between professional achievements and personal attributes. Encourage your recommender to write about your leadership qualities, teamwork skills, and commitment to excellence, but also ask them to share insights into your character, such as your integrity, empathy, and work ethic.

Tip: A recommendation that includes both professional and personal anecdotes helps the admissions committee see you as a well-rounded individual, not just a candidate with a good resume.

By following these expert tips, you’ll ensure that your Letters of Recommendation provide a powerful endorsement of your candidacy and help you stand out in ISB’s competitive admissions process.

Sample Letters of Recommendation for ISB Applicants

Below are sample responses for each of the four ISB recommendation questions. Each sample demonstrates how the recommender can provide a detailed, thoughtful, and impactful letter within the 500-word limit.

1. Please provide a brief description of your interaction with the applicant. (Word limit 500)

Sample Response:

I have had the privilege of working with [Applicant’s Name] for over four years at [Company Name], where I am the Senior Marketing Manager. During this time, [Applicant’s Name] reported directly to me as a Marketing Analyst and, more recently, as a Marketing Lead. Our working relationship has evolved from initial project collaboration to overseeing key strategic initiatives, where [Applicant’s Name] took on increasing responsibility.

One of our major projects involved launching a new product line for [Product Name]. In this role, [Applicant’s Name] was responsible for creating and executing the entire digital marketing strategy. This included market research, content planning, and overseeing the performance of our campaigns across multiple platforms. Their contributions were instrumental in the product’s success, which exceeded its initial target by 20% within the first quarter.

As their supervisor, I observed [Applicant’s Name] demonstrate excellent leadership, even when leading cross-functional teams. They were able to seamlessly coordinate between the sales, development, and creative teams, ensuring that deadlines were met while maintaining high-quality deliverables. What sets [Applicant’s Name] apart is their ability to balance creative problem-solving with analytical rigor—qualities that consistently drove strong business outcomes.

Additionally, [Applicant’s Name] has been an exceptional mentor to junior members of our team, often dedicating time outside regular hours to train them on campaign analysis and data interpretation. Their guidance has fostered a culture of collaboration and growth within the department. Our interactions have not only been professional but have also developed into a mutual respect that I value greatly.

Through these various roles, I have come to understand the depth of [Applicant’s Name]’s capabilities and commitment, making me confident in recommending them for the ISB PGP program.


2. How does the applicant’s performance compare to that of other well-qualified individuals in similar roles? (Word limit 500)

Sample Response:

Over the last decade, I have managed many talented marketing professionals, but [Applicant’s Name] stands out as one of the most capable individuals I’ve worked with. In comparison to their peers, [Applicant’s Name] consistently performs at a higher level, both in terms of results and leadership.

[Applicant’s Name] is particularly adept at taking ownership of complex projects and delivering results under pressure. For instance, during the launch of [Product Name], we faced unexpected market challenges that required quick decision-making. While other team members struggled to adjust to these changes, [Applicant’s Name] swiftly revised the campaign strategy by conducting an in-depth competitor analysis and identifying a gap in our market positioning. This adjustment led to a 30% increase in customer engagement within two months, outperforming other product launches led by equally qualified professionals.

Another area where [Applicant’s Name] surpasses their peers is in their ability to innovate. While many professionals tend to stick with proven methods, [Applicant’s Name] is always eager to experiment with new tools and strategies. For example, they were among the first in our team to implement predictive analytics for lead scoring, a method that improved our conversion rates by 15%. Their initiative to test and adopt new technologies put them ahead of others in the department.

Additionally, [Applicant’s Name]’s interpersonal skills and ability to lead diverse teams is unmatched. They are frequently sought after by other departments for their expertise and collaborative spirit. While other marketing leads are competent, [Applicant’s Name] goes beyond mere execution and actively fosters innovation and leadership within the team. Their performance consistently outshines other well-qualified professionals, making them an exceptional candidate for ISB.


3. Describe the most important piece of constructive feedback you have given the applicant. How did the applicant respond? (Word limit 500)

Sample Response:

One of the most important pieces of feedback I gave to [Applicant’s Name] was during a particularly challenging period for our team. In the early stages of their role as Marketing Lead, [Applicant’s Name] was highly detail-oriented, which sometimes led to slower decision-making. Their focus on perfecting every element of a campaign, while commendable, was impacting the overall pace of project delivery.

I advised [Applicant’s Name] to strike a better balance between precision and efficiency. In our field, deadlines are often tight, and waiting for perfection can hinder progress. I suggested that they prioritize key elements and make decisions based on the 80-20 rule—focusing on the aspects that would drive the most impact while accepting that not every detail could be flawless.

[Applicant’s Name] took this feedback very positively and immediately worked to adjust their approach. They developed a project management system that allowed them to set clearer priorities and delegate more effectively. Within a month, I saw significant improvement in their ability to make swift, informed decisions without sacrificing quality. This change became particularly evident during the execution of a large-scale campaign for [Project Name], where their enhanced time management and delegation led to a 15% increase in project efficiency.

Their ability to take constructive criticism and transform it into actionable improvement speaks volumes about their leadership potential and adaptability. This experience has not only shaped [Applicant’s Name] into a more efficient professional but has also allowed them to take on even more complex projects with confidence. I am certain that this quality will serve them well in ISB’s rigorous program.


4. Is there anything else we should know? (Word limit 500)

Sample Response:

Beyond their technical and leadership skills, [Applicant’s Name] possesses several qualities that I believe will make them an exceptional addition to ISB’s PGP program. Perhaps one of the most notable is their deep sense of responsibility toward their team and the broader community.

During the height of the COVID-19 pandemic, [Applicant’s Name] initiated a company-wide project to transition our marketing efforts to digital-first strategies, ensuring that our business stayed competitive during uncertain times. This was not a directive from senior management but rather an initiative that [Applicant’s Name] took upon themselves. Their forward-thinking and proactive nature saved the company considerable costs and allowed us to remain agile in a rapidly changing environment.

Additionally, [Applicant’s Name] has a keen interest in mentoring others, both within the workplace and in their community. They have been involved in volunteering for a local NGO, providing digital marketing training to small business owners affected by the pandemic. This speaks to their desire to not only advance in their own career but also uplift others along the way.

In summary, [Applicant’s Name] brings a unique combination of professional expertise, leadership, and social responsibility. I have no doubt that they will thrive at ISB, not only as a student but also as a valuable contributor to the diverse and dynamic community that ISB fosters.
