I applied online. I interviewed at Deloitte (Yoqne`am) in Mar 2025
Interview
After the initial HR call I got an invitation for a 3.5 hour long on-site technical "interview" in the middle of a working day (no late evenings or early mornings hours were available for taking the test).
I got to the interview and the person that was suppose to interview me was sick, and none of the other office workers had a clue I'm coming.
After about 20 minutes of waiting somebody eventually set up a computer for me to take the test on.
The test had 3 parts:
1) leetcode style programming task (easy)
2) 10 open questions about LLM, RAG, and vision tasks.
3) two "code filling" tasks:
task 1: An LLM is prodoucing wrong/inaccurate short answers.
the task is to examine the prompt for a LLM and to to tweak it hyperparameters (temp, num of tokens etc')
task 2: you are given a "legacy" code snippet that trains a pytorch vision classification mode, the code is messy, incorrect and lacks any documentation. Moreover, the trained model performs badly.
the task is to rewrite / fix the code, examples of errors in the code:
- the training val loader is not used for validation (they used the train loader)
- the mean loss calculation for each epoch was wrong.
- the model was not set to "model.eval" before validation.
- no metric logging was used.
After all of that you are required to fill in a survey about the "interview process" where they ask you about the "maximum appropriate length of the interview in your opinion" and such other stuff, and ask if you would agree to take ANOTHER such interview in the future.
I finished all of the tasks, nobody talked to me, I left the company offices alone and after about two weeks I got a standard rejection call.
Interview questions [1]
Question 1
open questions about LLM:
- how would you evaluate a RAG solution?
open questions about vision tasks:
- a model performs good on validation and testing data but fails in the real world, why?
- given two bounding boxes on an image, each tracking a car, how to tell which is the correct box for each vehicle when they intersect?
The interviewing process was smooth and clear from the start, it consisted in phases, first HR, then a technical interview with the Team Manager, then a technical interview plus take home coding exercice with the final client.
4 entretiens au total, rh technique, directeur et partner au total sur 2 mois de processus. c'était assez facile, échange fluide. feedback de la rh après chaque entretien, feedback rapide.
I applied through university. I interviewed at Deloitte
Interview
It was an online assessment featuring 3 coding questions in leetcode style. Ranging from easy to hard difficulty. I was not able to advance. Was a good experience. Would have preferred a little clarity in why I was rejected.
