Vorstellungsgespräch

Phone call -> hackerrank test -> final round -> hr round. The interview was difficult but the interviewers were great professionals. They always looked to help out and get the best out of the candidate. Fractal has great people. But overall the hiring process was very slow. Human Resource people can do a better job of following up and providing updates to the candidates.

Fragen im Vorstellungsgespräch

  • How can you reduce overfitting of a random forest model?   1 Antwort

    Ich habe mich online beworben. Vorstellungsgespräch absolviert im Februar 2020 bei Fractal (New York, NY (Vereinigte Staaten von Amerika)).

    Vorstellungsgespräch

    It started with an HR call about my background, why new job, salary expectation and some BQ. Then I received a coding test which contained 6 questions in Python and SQL. The camera is on and it's pretty intense. Need to think about some questions and I spent 2 hours on that. Then I had several rounds of interviews, involving ML, coding, projects I did, etc. Overall it's a smooth process.

    Vorstellungsgespräch

    It started with some Utterly useless technical test - programming. I think they are just trying to act smart which probably they are not as the test is for software engineer and not a data scientist.
    Don't waste your time applying here.

    Ich habe mich über einen Personalvermittler beworben. Vorstellungsgespräch absolviert bei Fractal.

    Vorstellungsgespräch

    OMG!!! I was insulted (implied that I was stupid ) and disrespected (my answers were constantly dismissed as wrong, although they were correct). The company is 85% Indian males. I am a white American female with a PhD. I do not think I should comment more. That was a horrible discriminatory experience!!! I declined to participate in the in the interview process further.

    Fragen im Vorstellungsgespräch

    • The interviewer asked about random forest and how it works. When I said that each decision tree in the forest considers a random subset of features, he disrespectfully interrupted me and told me that I am wrong. Then he scolded me for giving the "wrong" answer.   2 Antworten

    Ich habe mich online beworben. Vorstellungsgespräch absolviert im März 2018 bei Fractal (New York, NY (Vereinigte Staaten von Amerika)).

    Vorstellungsgespräch

    Step 1: Phone screen with HR - standard questions - biggest difficulty was understanding what the recruiter said, very strong accent
    Step 2: Coding test - 3 problems
    Step 3: Technical Interview - questions about algorithms and stats
    Step 4: Interview with consultant
    Step 5: On-site interview - 4 back-to-back 40 minutes interview, including case studies and very theoretical statistics questions - very tiring and intense - totally disorganized

    The process is very time consuming and the communication with the recruiter is just ridiculous. You send e-mails and they either won't ever respond you or will take a month to respond. At the end of the last stage, I was told I would receive an answer over the next days and the answer never came, even after trying to get in contact with the recruiter (and, obviously, being ignored). I honestly have never experienced such an unprofessional way to deal with people.

    Vorstellungsgespräch

    I applied through their web portal & got shortlisted for an online coding test. They assigned me a Hackerrank test of 1.5 hrs. The test comprised of 7 questions : 5 MCQs[Multiple Choice Questions] and 2 programs. The MCQs were in general related to Data Science. The 1st programming question was based on dynamic programming. The next question was related to creation of a model with respect to the given dataset. This model was expected to have at least 65% accuracy in the test dataset.
    To tackle this interview round, one thing you've to keep in mind is time management. Otherwise, you'll spend a lot of time in the dynamic programming based question. My suggestion : take down the data science based question first, because it doesn't require much time (provided you know how to build a small & simple model), and then go for the other one. I did the mistake of investing a lot of time on the dynamic programming based question. Result : Couldn't solve it and also failed to pass the test cases of even the data science program. Hence rejected.
