Candidate-reported interview process
So the process had two phone interviews that happened pretty close together, like within a week. The first one, I had to solve a programming question. The very next day, they had me schedule the second interview, which was all about my machine learning knowledge. Then, about 15-20 days later, I got the call with the offer, and I took it.
Had a quick interview process and got a response in less than a week. The first step was a 30-minute HR phone screening. Then, a 30-minute video interview for coding on HackerRank. The third interview was a 30-minute video call focused on Machine Learning.
Had a video interview where I was asked to calculate precision, recall, and f1-score for a scenario. Also, they asked about different ML models for a hypothetical question, like which regression models to use and their pros and cons. Need to know tree-based models well.
