Machine Learning Engineer Interview Experience - Canada
Process
I saw the post on Linkedin and applied through their portal. They sent me the HackerRank link (2 programming tasks: 1 neural network + 1 data science, 4 theory questions). Then I had 3 more rounds, all technical: 1 with an engineer, 1 with a global team lead, and 1 with a researcher. The round with the global team lead was great, he had a deep understanding of all the mentioned techniques, but the researcher was a bit weird, he started the interview with a bad attitude.
The HR was unprofessional, she didn't tell me anything about the hiring process. I don't know how many rounds there were, technical or behavioral. I asked her twice, and she only replied after I cc'd the team lead. She duplicated my interview as well. I agree they pay well, but respect for people seems to be lacking in my case.
Questions
Preprocessing: how would you optimize preprocessing if you had 1 million records in the database, just a little about CI/CD
ML/DL: Embeddings (statistical methods + NN), similarity, what is RAG, interpolate, and extrapolate. If you have data from 2 years ago, how would you predict this year? Evaluate 2 chatbots, 2 models.

Tower Research Capital Work Experiences
- 4.0Smart, helpful bunch of co-workersSoftware Engineer (Internship) • Former EmployeeGurgaon, IndiaMay 9, 2020Pros: There is nice pay, WLB, and helpful co-workers.Cons: There are not many new things to work on.
- 3.0Good workplace but biased senior managers making the environment toxic in IndiaCore Engineering Software Developer • Current EmployeeGurgaon, IndiaNovember 20, 2019Pros: I have worked at Tower for quite some time. There are a number of positives: 1. You get to work on a number of challenging problems. 2. Your colleagues are mostly smart (except some which would I will highlight in cons) 3. Great food 4. Good payCons: 1. Some of the managers show a lot of favouritism, especially towards people who they have known prior to joining Tower (either due to personal connect or other previous organization). Hiring process/Interview process is also not followed in the right manner due to managers' influence over the interviewees. Even people with poor preliminary test performance go through. 2. All of this goes unchecked and people close to their managers get better appraisals, better bonuses and better work. 3. Any voice of dissent is often suppressed since devs don't have direct contact with the upper management based out of other locations (other than India).
