I applied through a staffing agency. The process took 3 weeks. I interviewed at Paytm Labs (Toronto, ON) in July 2020
Interview
For a first interview (no recruiter call on the opp), this was focused on minute details from three very different areas of the ML ecosystem (advanced stats, spark, search trees). Was not expecting this level of detail prior to the coding interview. The interviewer was rather cold during the interview and not direct when answering my response questions about getting to know more about the company.
