I applied online. I spoke with a recruiter. He told me that the process consists of only two stages, an online test and a technical interview. The online test was hackerrank test. It was quite difficult mainly due to the 1-hour time limit. I passed the test and had a technical interview. The interviewer's questions were difficult but fair. This should have been it, however, I was then let know that there's going to be another two stages (a take-at-home assignment) and a technical interview about this assignment. At this point, I should have declined to continue (as this is very unprofessional) but decided to give it a go since I had already invested the time. The assignment did not include a time limit but based on the requirements it was a 16-hour task (assuming that you want to everything perfectly). Stupidly, I decided to invest the time to complete the task. I was extremely proud about my solution and I was certain that I had passed this stage. A week later I was told by the recruiter that I didn't. Verdict: A waste of valuable time. To the people applying: Ask to know about the hiring process. Demand to have the stages in writing from someone within the company. Do not agree to go over a process that has more than three stages.
