straightforward interview, covered the typical data scientist questions. technical sql, then python then onsite with interviews with pms and other data scientists. overall, not sure if it was the best way to evaluate candidate skillset, but didn’t stray from the typical path

Entrevista

The interview process was insulting, when it came time for the technical interview I told the recruiter multiple times that I program in R (the job posting and interview request said R/Python). When it came time for the interview the interviewer said it would be in Python, I said that I told the recruiter I program in R and the interviewer said that she didn’t even think the interview question could transfer to R. It did not. I guess I should’ve prepped Python instead, the question was easy enough that had I prepped my 5 year old Python notes that I could’ve easily passed it. I prepped a bunch of stats and data transformations in R instead, since that’s what I currently do in my DS job. The interviewer didn’t even know enough R to help me along with the question. For the second part, I got every SQL question right. Then I got a generic rejection from a no-reply, not even from the recruiter I was in contact with. The whole process was extremely insulting and I won’t be applying to Square again.

Entrevista

Referral. Recruiter then SQL screen. Worst tech screen interviewer experience I’ve had (have done similar screens including FAANG and other startups- always walked away with good interviewer impressions regardless of outcome). Interviewer was disorganized, not interested in hearing my thought process, didn’t communicate basics like timing and how many problems were left til it was too late. Problems themselves weren’t hard. It would’ve been much easier to complete the problems by myself, with a timer, and no interviewer.

first a behavioral screen and then a technical coding interview in python which was timed. The coding interview was easier then I expected but they already made a hire by the time they got back to me about it.

About two weeks. Two technical/programming phone screens in SQL and Python, followed by a virtual onsite with technical interviews and business partner interviews. Received result in the next 48 hours.

Preguntas de entrevistas
  • NDA. There was a very easy Excel problem. I chose to code instead. The interviewers are very junior and had difficulty explaining the questions as ESL persons. They also very passively participating in the interviews. They did not ask any question to assess the depth and breadth of ML/statistics knowledge. Mainly bc they're juniors themselves. So the hiring decision is pretty random.

Entrevista

There were two rounds of technical coding interviews over the phone. Followed up by a phone conversation with the hiring manager talking about my past job experience as a data scientist. They decided to bring me on-site afterwards for a full-day interview. During the on-site interview, they forgot to include an interview to test me on a specific data science aspect and ended up having to schedule another interview. It is very unprofessional for such a slip up. During the last coding interviewer, the interview just assumed i didn't have the technical experience for the job even though I have listed many years of experience. His attitude was condescending and borderline discriminatory for a minority like me. For a lot of questions about data science project experience, there are no clear cut answers so I tell him my approach. What people do all depends on the situation but the interviewer wanted a clear cut answer.

Entrevista

I applied online and contacted the recruiter through LinkedIn. We arranged a phone call the next day. They called me and asked me about projects that I have been working for and questions about metrics that we should use for classifying their customers segments. The interviewer was very kind. I wasn't prepared enough and didn't get the in site. It is my beginning in the interview process but it was a good first experience.

Me postulé a través de un reclutador. El proceso tomó 2 semanas. Acudí a una entrevista en Square (San Francisco, CA)

Entrevista

I was contacted by a recruiter and chatted with him about the position. It sounded interesting, and we scheduled a phone interview. The phone interview was pretty straightforward. Just writing some basic Python code in a screen sharing environment with someone from the team I was applying to. It went pretty smoothly, and I was invited on-site for an interview. The first two on-site interviews were pair programming. All the interview stations were in use by others, so we ended up doing it in a tiny conference room with the interviewers' laptops. The first exercise was programming up a simulation of the Monty Hall program. The interviewer was pretty vague about the requirements, but we eventually worked something out. The second exercise was some data exploration. The recruiter hadn't told me that they'd want to do this in pandas, which I was rusty on, but I managed alright. Lunch was pretty nice. I was supposed to eat with 4 or so people from the team, but I only ended up actually ever talking to one. The rest kind of sat away from my escort. The afternoon interviews were more traditional white board interviews. I got asked to describe my favorite machine learning algorithm, which the interviewer also knew a lot about, so that was fun. I got asked some analytics/statistics questions by an interviewer who'd clearly been pulled in at the last minute and wasn't prepared. She kept forgetting key bits of information. The final interview was with the hiring manager. It was more statistics and personal questions. Overall, nothing was too difficult, and it was pretty pleasant. I didn't get a tour around their new offices because of security reasons, but the bits I saw seemed nice.

Preguntas de entrevistas
  • (The interview drew a hypothetical histogram of number of purchases per user.) There are a lot of users that make a small number of purchases, and few users that make a large number of purchases. So the histogram is peaked near zero and has a tail off to the left. Based on this, what do you expect the plot of average revenue per user to look like?
