      C++ Developer Interview

      Dec 9, 2020
      Anonymous Interview Candidate
      No offer
      Negative experience
      Average interview

      Application

      I interviewed at think-cell

      Interview

      9 hour coding challenge, then 2 more rounds of coding. Extremely low retention rate in the trial period when they can fire you whenever. Don’t even bother with a company this toxic.

      Interview questions [1]

      Question 1

      Data structures question, coding challenge

      Dear Candidate, Thank you for your review. We are sorry to hear that your experience did not meet the standards we set out to reach. Indeed, we at think-cell have high expectations when selecting and keeping the best C++ developers. Still, think-cell is a company that developers truly like. We now have over 20 full-time developers, and in think-cell’s 18 years, only two have ever quit on their own. The fact that the company is owned and managed by seasoned computer scientists certainly contributes to a working environment that makes exceptional developers come and stay. Thank you for your application. We wish you all the best.

      Easy interview

      Application

      I applied through other source. I interviewed at think-cell

      Interview

      After spending hours to do a test - they reject the application without even bothering providing feedback (and that despite the fact the test was well done and passing all the tests) - that is not a professional behavior and lacks respect for the time people invest in the process.

      Thank you for taking the time to share your experience and feedback. We’re sorry to hear that you found the process frustrating, especially considering the time and effort you invested. We understand how important it is for candidates to feel that their work is acknowledged and respected.

      I interviewed at think-cell

      Interview

      First it was a coffee chat and then a 10h technical assesment, without any feedback for their side. It was frustrating because after investing a lot of time, they don't even tell you nothing.

      Question 1

      Implement the method 'asign' for a map-based data structure

      Thank you for taking the time to share your experience and feedback. We’re sorry to hear that the process felt frustrating. We aim to create a recruitment experience that is both fair and respectful of candidates’ time. Our technical test is designed to assess problem-solving skills in a realistic way and help us identify the strong technical abilities required to maintain the high standards of think-cell’s products. The platform allows up to 10 hours to complete the task to give candidates flexibility, for example to take breaks if needed. In practice, many candidates complete and submit their solutions within around 2–4 hours. Regarding feedback, we also understand that not receiving detailed comments on a submission can feel disappointing. Unfortunately, providing specific feedback on the assessment would compromise the integrity of our evaluation process and our ability to continue using this test consistently with all candidates. We appreciate your understanding on this matter. Best regards, People Team
