Ok, huge red bells ringing for this company and their data science department, which I will attempt to go through below. But long story short, whether you are an applicant, employee, or a client, I would be very concerned, as this company doesn't treat it's applicants or employees well.
Concerns:
1) The HR didn't even give me a call when I applied and explained what the position is about. I only found out what department the position was for when having my first interview.
2) My interviewer was fresh hire (less than 2 months on the job), not from my future department, and not a data scientist. I believe he was a strategy consultant. To be fair, the job advertised was Data Science Consulting, but these people are way more into consulting than data science. More on this below.
3) As per employee reviews on Glassdoor, I nearly broke out in laughter during the interview because the guy looked like he hadn't slept in weeks. He made minimal effort to explain anything and was wearing a hoodie. I don't blame him, I quite liked him. But he just didn't have any answers for me nor seemed interested in talking to me. He had a script that he adhered to and spent exactly half an hour on zoom with me, not a minute less or more. Question is... if they have a script and they're not related to the job posting, why doesn't HR do these interviews? and why waste an employees valuable time?
4) The script asked extremely basic and simplistic questions, leading me to believe that the job offer would be based on how likeable you are and not your actual skills. The brain teasers were fun, sure, but really not relevant to data science. I was very confused by what they thought they were measuring and how they could have enough info to reject me after getting that information.
5) There were no data science questions. I could tell that to get the job, you had to have an MBA or sales experience. It's a bit ridiculous, honestly, but what I see from the employee reviews is that they essentially focus on customer service and being likeable consultants and not on actually doing work. Even their website proudly states the number of ML models trained as some kind of statistics meant to show how good they are at science. Clearly, they do not understand data science. This company will fail and soon unless the leadership makes some serious changes in their attitude and logic. The fact that a new hire in an unrelated position had to interview me tells all you need to know if you're a data professional looking to apply to this company.
All in all, it wasn't a terrible experience, since I wasted limited amount of time and got some valuable interview practice, but I can tell you that this company is basically selling dreams if they're looking for data science professionals by asking them only client-handling questions and mathematical brain teasers and literally nothing else.
P.S.: at no point did I have enough time to ask much about the position nor was I asked about my aspirations or actual experience. I think having an HR round is essential to see if it's the right fit, and they just skipped it and wasted their employee's half an hour, so if I actually got an offer, I would immediately turn it down just based on that alone. I don't think they hire people that actually want to work there.
