      Software Engineer Interview

      21 Nov 2017
      Anonymous interview candidate
      No offer
      Neutral experience
      Difficult interview

      Application

      I applied online. I interviewed at think-cell in Nov 2017

      Interview

      There're 3 phases in the interview, they are take-home assignment, Skype interview and on-site interview. The take-home assignment asks you to implement a class method that has something to do with std::map. it isn't extremely difficult however there're corner cases you need to handle carefully. Both the correctness and the performance of your code will be evaluated. I didn't pass the first phase, for reason I don't really know(they didn't say).

      Interview questions [1]

      Question 1

      it has something to do with std::map is all I can say.

      Software Engineer Interview

      Positive experience
      Difficult interview

      Application

      I interviewed at think-cell

      Interview

      The take-home assignment was a technically engaging challenge centered around building a small library using advanced C++ template techniques — a great opportunity to showcase skills in modern C++. The task itself was well-designed and thought-provoking. For engineers who enjoy template-heavy programming, this is a process where you can really shine and demonstrate your depth of knowledge from the very start.

      Difficult interview

      Application

      I interviewed at think-cell

      Interview

      I did not proceed very far in the process, as I decided to withdraw early. Before having the opportunity to speak with anyone at the company, I was asked to complete a take-home programming assignment. The task involved implementing a small library and relied heavily on advanced C++ template techniques. While the assignment was technically interesting, I would have preferred to have at least an initial conversation with someone from the company before investing significant time in a take-home exercise. For candidates who enjoy modern C++ and template-heavy programming, the process may be a good fit, but I personally found the order of the process somewhat unusual.

      Thank you for taking the time to share your experience and for your thoughtful feedback. We understand your perspective that having an initial conversation before investing time in a take-home assignment is valuable. The process you described has since changed: as of September 2025, every candidate has an introductory conversation with us before receiving the assignment. Thank you again for sharing your perspective, and we wish you all the best. Best regards, People Team

      Difficult interview

      Application

      I applied online. I interviewed at think-cell (Berlin) in Jan 2026

      Interview

      Initial interview talking about CV and previous experience as well as what technologies I was familiar with. Online technical assessment, one exercise. You have 10 hours to complete it but I used it all to make sure my answer was correct. The key of the exercise is STL containers and algorithms.
