I applied online. The process took 5 days. I interviewed at Toast Inc
Interview
HR screening, interviewer was 15 minutes late for a 30 minutes call, asked really basic question, obviously just looking for specific keywords without any understanding of anything in the field
4 Rounds with presentation, coding test and coding test review, with lunch reimbursement on the long interview. Between the interviews it usually take 3-4 days to the next round. The coding test is around 3-4 hours long.
Interview questions [1]
Question 1
They ask for another senior DS to review your coding. I believe I have working on the coding test perfectly and answer all her review questions, then after 4-5 rounds including HR interview they decline my application saying they hire someone else with same level of my interview performance but more year of experience, which could totally be a waste of time.
