Technical Behavioral

Right after I applied, I had to take an online technical test. It was supposed to be 3 hours long and done under camera surveillance, no double screens, etc. They wanted it done by the end of the week, which meant I had to cancel my weekend plans. Honestly, asking for a 3h test on such short notice felt like a red flag, but I ignored it and aced the test with a perfect score on all 3 exercises. Then, I had a meeting with HR. Unfortunately, just two days later, they rejected my application without any explanation, even when I politely asked. That was another red flag.

Behavioral Technical Coding

The interview process was really good and upfront. Every step was explained clearly, and I liked how professional and open everything was. The interviewers were friendly, and their questions made sense, giving me a good chance to show what I know and have done. I felt pretty good and like they cared during the whole thing, which shows the company tries to be nice and fair to everyone.

Technical Coding

I applied for the job and then had a 30-minute call with a recruiter. After that, there was a 3-hour assessment, which felt a bit long. Following the assessment, I had a video interview where the interviewer was mostly quiet. They used Codility for a coding test, giving 80 minutes to solve 3 tasks. One task was multiple-choice React, another was a like/dislike button in React, and the third was a React pagination task. I'm pretty sure I got eliminated because of my score on the last task due to the unit tests and time limit, even though I did the first two perfectly. I don't think testing unit tests within a 30-minute timeframe is a good way to evaluate candidates and doesn't really prove anything. I'd rather have a free coding exercise that allows for better evaluation.

Confirmed questions2 questions
  • Create a mini React app for a like/dislike button.
  • Build a React component for pagination.
