      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.

      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

      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.

      I interviewed at think-cell (Berlin)

      Interview

      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.
