      Entretien

      The first round was with a recruiter. It was a the only chat of the recruitment process that was nice. The second round was with a simple one-hour textbook-like interview in the style of: Can you describe batch normalization? Can you tell about SIFT and HOG image descriptors? Thereafter were two coding rounds and three other rounds of textbook questions, a paper presentation and practical questions. All in all, the process was way to long and impersonal. At no point I was asked about my personal experiences and interests. People, apart from maybe the recruiter, did not seem to care. Moreover, even after several hours of being tested I could still not get much info about the team and the job.

      Pretty standard. Recruiter call with 4 rounds of interviews. Eventually got a call saying they are not rejecting me but also not saying a yes, which is pretty unheard of. I consider them to indecisive and unprofessional and will recommend to avoid as it reflects their internal working process.

      Pretty standard bookish questions you can find on the internet. BatchNorm, Stats etc.

      Overall, I enjoyed the process. It was very transparent, I was given all the information needed to get prepared for each step. Unlike most of the companies that reject a candidate by email without any feedback, I was given a call by the recruiter who took the time to explain what the team liked and did not like about my profile. The feedback was constructive and I found the decision quite fair although I am upset. I applied on the company website. The interview process started with a call from a recruiter to discuss the position, my background, my expectations, and the overall interview process. The first step of the interview is a 1-hour textbook question with two employees from Onfido. The questions cover four main categories: probability, statistics, machine learning, and deep learning. The next step, if the previous one is successful, is the panel interview consisting of 5 rounds interview with 5 different people from Onfido. Each round is 1 hour long, and there is 1 hour break between each round. - For the first two rounds, I had to solve one leet code-like coding exercise for each. -The next round is the applied deep learning interview in which I presented a deep learning paper of my choice. I also presented a previous project I worked on. This round is closed with some practical questions about training and using deep learning. -Next comes the ML and DL fundamental interview. This interview is about answering textbook questions on ML, DL, and Maths (statistics, probabilities, calculus) using a whiteboard. -The last round is about chipping and monitoring ML and DL systems in production and how to work alongside ML engineers and MLOps. I did the whole process remotely.
