      C++ Software Engineer Interview

      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.

      Difficult interview

      Application

      I applied online. The process took 1+ week. I interviewed at think-cell in Sept 2018

      Interview

      Very business-like, direct, and efficient. Each stage of the application process followed swiftly from the previous one. Well-designed use of cloud technology to filter and evaluate candidates, combined with the human touch of a professional, cordial HR department.

      Interview questions [2]

      Question 1

      Remote work not available. Would you be willing to relocate to Berlin, Germany?

      Dear candidate, Thank you so much for your valued feedback, we are delighted to hear you enjoyed the application process. In order to treat each candidate in a fair manner, we offer the same opportunities to every developer applying for the C++ position. Therefore, we are unable to share information about our tasks, solutions or mistakes and kindly ask applicants not to disclose any information received from us about our tasks. Indeed, our only office is located in the center of Berlin, our team is like a small family, that sees each other every day. Although you did not receive a job offer, we would like to thank you once again for taking part in the recruitment process and wish you all the best in your future career.

      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. We understand that not receiving detailed feedback can create the impression that your effort was not fully recognized.

We appreciate your understanding in this regard. Best regards, People Team

      Average interview

      Application

      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.

      Interview questions [1]

      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
