I applied through a recruiter. I interviewed at Nabla (Paris) in Jun 2026
Interview
A recruiter contacted me, and we decided to stay in touch. I reached out to them a month later to ask about starting the recruitment process. They were very clear and very friendly throughout!
There was:
- Discussion with the recruiter (very informal, to clarify the details)
- Two technical interviews: One on leetcode/vanilla javascript - another one for system design
I got accepted and moved on to the last interview round, which is half a day in their office with 4 interviews:
- A React test - A coding task - A project presentation (I picked and prepared a project beforehand) - A culture fit
The overall process took roughly a month, but I had some stuff going on, and they had a week-long seminar in the middle. (I believe it can be faster if you're in a rush.)
Interview questions [1]
Question 1
What was the toughest feedback you had to give someone?
Don't bother apply, first recruiter call, followed by classical SDE type interview, the issue is that the recuiting team send you rejection email like "you know what, you are a complete trash" implictly, they represent the reputation of the company, they should learn how to speak politely. If you like to be insulted, apply for a job! then their recruiting team will show their expertise to let you down and feel bad.

Question 1
leetcode hard question, be prepared with multiple solutions, the guy interviewing you only knows the solution he has in his brain, if you don't show him that solution, it's over

The interview process was quick, I had good impression from the employees. Unfortunately did not complete the technical task, which was a Leetcode exercise on stack. They expect you to solve the task completely on your own and quazi know the answer in advance, better do not ask too many questions or help from the interviewer. I recommend going through the most popular leetcode questions and memorizing the answers - then you will pass through the recruitement process.
Thank you for considering us for your next role. We really appreciate your feedback and will be sure to share it with the team.
