      Candidature

      J'ai postulé via une agence de recrutement. Le processus a pris 3 jours. J'ai passé un entretien chez think-cell (Berlin) en août 2021

      Entretien

      The interview seems completely automated to me. Once you receive the task you have 9 hours to complete it and submit, then an automated test will run and automatically reject if fail. I guess nobody even take a look at it or your CV or anything, just using your email address will do, probably due to the massive amount of applications and rejections. Cannot disclose the test, it's obviously about C++ and algorithms, and you must be very good because apparently most of the people found the solution that miss special test cases..

      Dear Candidate, Thank you for your application as well as review here at Glassdoor. We are very sorry that your experience was not as we expect it to be. We consider different profiles for our C++ developer position, independent of the former specialization and years of experience. For think-cell, it is more important to evaluate programming abilities first, rather than the resume. We are looking for smart, creative developers with a solid theoretical background. Our team of developers consists of those with 15+ years of commercial experience in various fields, to fresh graduates in Computer Science, Physics and Mathematics. A university degree or work experience with C++, together with a fresh and creative problem-solving approach would be an excellent combination for this role. All of our recruitment steps are task-based, therefore, the selection decision depends on the abilities demonstrated during the tests. Thank you again for your time and we wish you all the best in your career development. Kind regards, Julia I HR Manager

      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. We understand that not receiving detailed feedback can create the impression that your effort was not fully recognized. However, providing specific feedback on the assessment would compromise the integrity of our evaluation process and our ability to apply it consistently to all candidates. We appreciate your understanding in this regard. Best regards, People Team

      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.

      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

      It took me 7 hours to complete. The ui hanged at some point and I had to restart. Otherwise it was a fun experience. I could related to comments that the process is lengthy. It is. But so is the job itself, you have sit at your desk and solve real problems.
