      Senior Data Scientist Interview

      21 Dec 2019
      Anonymous interview candidate
      Philadelphia, PA
      No offer
      Negative experience
      Easy interview

      Application

      I applied online. The process took 5 weeks. I interviewed at TE Connectivity (Philadelphia, PA) in Dec 2019

      Interview

      Note that if you interview here in the next few months from my interview , they are putting together a new analytics team and are trying to hire a lot of people (should give you leverage). I quickly had a 1-hour technical phone screen with 1 principal data scientist on the team. I could tell they were sharp but I wasn't impressed by their interview questions (see the interview questions listed below -- these are not quality data science questions that i would ever use). The quality of my experience went down significantly when I had probably the worst interview of my life with the new lead of the analytics team (and when I say new, I mean she was 4 weeks into the job when we talked). There were some huge red flags. She said that the interview was going to assess culture fit (I've been through many of these types of interviews before). She clearly did not know what culture fit is because instead of discussing culture, she wanted to try to do a technical interview. I got a particularly strange question right in the middle of this: "How many models have you trained in the last 3 months?" This is a completely tone-deaf question that strips away any complexity or nuance from work that you might be doing. She had strange views on how to approach model-builds with business teams (she didn't why it's important to discuss the feasibility of their implementation). Definitely the weirdest part of the interview was when she asked me, halfway through, if I was nervous. Imagine briefly that you're asked this question. How do you answer that? It's a question with one conceivably correct answer: "No." And for me that was the truth. Really I think I was stunned by how badly I was being interviewed. At the end of the interview I was told I would hear back about next steps in the next few days (this was a lie). My e-mails to both the manager and the HR rep I'd been working with went ignored. Instead, I had to find out there'd be no offer from the technical interviewer. I feel like I dodged a bullet. Be careful interviewing here -- you may find yourself with an incompetent, dishonest boss.
