IESE Assessment Day 2023 - 2024: Everything you Need to Know

Updated: Feb 4

Getting ready for an interview at IESE? 

Great work on getting to this stage! IESE is one of the world’s top business schools, ranked #3 in the FT, #10 in QS, and Bloomberg’s #2 in Europe for 2023.  

This year’s IESE MBA class is composed of around 350 students, with an average age of 29 and approx. 5.4 years’ work experience. The class is 35% female and 85% international (non-Spanish). The average GMAT score is 670, with a score range of 580 to 750. The average GRE score is 317 (161 Quant and 156 Verbal). 

Applicants who are invited to the IESE interview may also be invited to an Assessment Day. 

In this IESE interview guide, we’ll help you prepare for the Assessment Day and the personal interview by priming you on their structure, the questions IESE has previously asked interviewees, and give you our top tips to ace the IESE Assessment Day and interview. 

Assessment Day

IESE candidates may or may not be invited to an Assessment Day. At your Assessment Day, you’ll simulate a classroom environment where you will work on a case discussion in a group setting.

This is a unique feature of the IESE interview which offers a taste of IESE’s Case Study methodology and gives applicants the chance to demonstrate their collaboration skills and fit with the school. The Assessment Day takes place one time per round of admissions, except for Rounds 3 and 4 because of the shortened window between interview and decision. 

If you are invited to an Interview but not to an Assessment Day, don’t worry: historically, IESE has admitted applicants who were not invited to an Assessment Day. Candidates who may have already interacted with the AdCom several times may be exempted due to limited spaces.  This also applies to those who are unable to attend the Assessment Day for other reasons; you are expected to inform the AdCom in advance if you are unavailable. However, if you are available and invited, it is encouraged for you to attend.

If you are located near an IESE campus in Barcelona, New York, or São Paulo, you may be invited to attend an in-person Assessment Day. Otherwise, you will likely attend your Assessment Day online. There is no difference in how you will be evaluated in either case.

The virtual Assessment Day will last 2.5 hours. The in-person event may be scheduled for longer. Reports indicate that participants’ pitches and demonstrations tend to overrun, so it is wise to block out extra time afterward to be safe. Here’s how the Assessment Day is structured:

  • Candidates receive the Case Study approximately one week in advance.

  • When the event begins, there is an introductory discussion

  • After introductions between students and facilitators are made, applicants start the group case discussion

  • Applicants are sent to smaller groups to discuss the case and make a decision as a team

  • Applicants return to the bigger group for the final case discussion

  • Ice breaker event and close

As mentioned, candidates will receive the Case Study being discussed approximately one week prior to the Assessment Day. The candidate will be expected to have read and analyzed the Case Study when they enter the group. In R1 2023, IESE provided the following preparation questions for their case study:

  1. Who is the main protagonist in the case? 

  2. What is the key decision being faced?

  3. How would you make that decision? 

  4. What data and information from the case support your decision?  

  5. How would your decision affect the other stakeholders involved?

The Case will come with a set of instructions that the candidate must follow. In short, the candidate is expected to present on the actions they would take if they were the protagonist of the Case. No additional research will be necessary as all information should be provided with the case. You may have to do some number-crunching depending on your decision. Again, this should all be done in the week leading up to the Assessment Day.

It’s useful to prepare a short pitch about who you are and what you do to make the introductory exercises go more smoothly; they often ask you to share something “unusual” about yourself. The assessment day will include two or three group sessions where candidates are able to share their work on the case study. Finally, there will be a group activity. 

Each group assessment will be overseen by an Admissions Committee or alumni evaluator, and students are advised to behave as they would in a normal Case Study class setting. Criteria for the Assessment Day aren’t released in order not to bias candidates toward or away from particular behaviors. Although it goes without saying, IESE is looking for skills that benefit a professional environment. It also helps to remember that diversity is a core value at IESE, so highlight what makes you unique!

That being said, previous attendees have noted that parts of the Assessment Day can be quite boring. Nevertheless, remember to stay attentive and professional. Just because you aren’t speaking doesn’t mean you aren’t being evaluated. Your goal is to showcase your teamwork, critical engagement, and decision-making skills. 

The Assessment Day is designed to be a space for you to share your thought process and experience. As is usual with Case Studies, show initiative and speak, help others out, and be firmly present without hogging the spotlight.

The IESE Interview

In addition to the Assessment Day, IESE applicants will have a personal interview. 

The IESE interview typically lasts for 45 - 60 minutes. IESE interviews are generally conducted by the Admissions Committee who are often IESE alumni themselves, and the school has, over the last couple of years, introduced a limited number of non-Adcom alumni interviewers as well.  

The interviews are non-blind. That means that the interviewer will have read all your application material and watched your video essay. Given that IESE’s questions range from standard MBA questions to questions based directly on your application, it’s important to know what to expect. You will be asked follow-up questions, so review your application in depth before your interview. 

The interview may be conducted online or in-person, depending on your location and the preference of the interviewer. In-person interviews are more likely in places where IESE has main campuses: Barcelona, New York, and Sao Paulo. 

What IESE is Looking For

IESE is training future leaders with a vision to create a positive impact in the world. For IESE, the responsible leader has the following qualities: 

  1. Drive

  2. Confidence

  3. Academic skill

  4. An international viewpoint

  5. Excellent communication skills

  6. Can work well as a leader or a member of a team

  7. A clear set of values

Think about how you can demonstrate one or more of these skills during your Assessment Day and the interview itself.

Tips to Ace the IESE Interview

Here are a number of IESE-specific tips that we have developed in working with hundreds of clients. 

  1. Be prepared with ideas, stories, etc. that aren’t directly picked out from your submitted application material. You may also need to prepare a new perspective on the stories you have already discussed. Keep IESE’s principles of leadership in mind. 

  2. When you answer behavioral questions, keep your core narrative in mind at all times. You are presenting yourself as a whole; your stories need to be consistent with your goals and why you are interested in IESE. 

  3. The interview is really to see how you can fit into IESE’s fairly small cohort. Diversity is celebrated at IESE, so focus on how your specific strengths will benefit the cohort and the school. 

  4. Even if your interview or Assessment Day is online, dress well. Wear socks and shoes. You can apply our tips about making your video essays perfect.

  5. In case you receive an unexpected question, pause before you answer. You can even ask for a moment to think. If you don’t have a suitable example, you may use a hypothetical scenario and explain what you would do (although real life is preferable when possible). 

  6. Don’t forget to send the interviewers a follow-up note! You’ll learn the interviewers’ names before the interview, so you can find their email addresses with little difficulty. 

Writing and rewriting your answers to the interview questions is one thing. To really prepare for the interview and Assessment Day, make sure you do mock interviews to simulate the real-life thing! Book a free 20 minute chat with one of our expert consultants to get started.
