      Candidature

      J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez C3 AI (New York, NY) en sept. 2019

      Entretien

      After going through an initial resume screening, was given an online coding test with a horrible IDE (Hackerrank). Questions were designed to confuse and nitpick. Received automatic email rejection after 1 day of taking the test saying "your scores were not within the passing range."

      Questions d'entretien [1]

      Question 1

      8 multiple choice questions and 1 coding question. The former covered neural networks (how to avoid overfitting training data), decision trees (what are they, and choose the best one given 4 choices), logistic regression (analyze a classification problem where precision and recall are good for one label but not for the other), k-means ("all of the following are true except..."), SVM optimization (how will increasing the weight of the slack variable term in the loss function affect things), SVM loss function (what it looks like), variance in probability (basically summing random variables with constants out front, and finding the overall variance). Coding question involved reading files and writing new ones.

      Resume screening -> technical assessment -> 4 rounds of interviews: - personal projects, simple questions not there to trick you - situational questions: "what would you do if..." - machine learning: starts from the very basics (stats and probabilities) to more up to date models - coding: medium leet code

      Entretien

      I applied directly after seeing a job advert on LinkedIn. There are MCQ and coding assessment on Hackerank, followed by a screening interview. It all went well and got invited to the technical day. To prepare for the technical interview, I went through all materials and questions shared by others on this website and once I was half way, I noticed that the questions tend to be similar, except the pairwise coding. I recommend you go through questions here to be better prepared for the technical day. The interview was generally okay and the team was nice. Started off with Case Study (30 mins); followed by ML questions (30 mins); and finally coding (1 hour). There is barely time in-between to switch so expect to transition very quickly. For the case study, think out loud it helped me to figure the actual problem, as they only share the problem and you figure the rest out. The coding was fair, I had done a couple of Leetcode but they started off with Linear regression etc, kinda caught me off guard and wasted 35 mins on it. Though the program ran, the interviewer said there isn't enough time to complete second question, and we shared our coding experiences and clarity on a few questions. I am pretty confident in stats and ML knowledge but the issue could have been coding; so make sure you are up to speed with anything that can be thrown at you. Two days later I received a rejection email. No reason after having spend so much time is a bit disrespectful but we move on.

      Questions d'entretien [1]

      Question 1

      Case study: Waste reduction in chain stores. They simply stated that and I described it as a demand forecasting problem that can be solved with Linear Regression. Besides clarification questions, It was fine and they took it. MLQ 1. Difference between Supervised and Unsupervised Learning, and give examples 2. Difference between bagging and boosting; 3. Bias and variance, and explain in the context of Bagging/boosting 4. Performance metrics; what does AUC mean, interpret AUC of 50% 5. Gradient descent 6. Overfitting and Underfitting and how to overcome them in Decision Trees Coding: Implement linear regression, numpy, and plotting importance scores
