I had a call with the recruiter (consultant).
After reviewing my CV, I was given a HackerRank test. It included 4 coding questions, 1 descriptive answer, and 10 days to complete.
There was an option to stop the tests in between and continue later.
I solved all the HackerRank problems. It was difficult to estimate the correctness of the descriptive questions.
Overall, I was very positive and looking forward to the interview. However, after 10-12 days, I received a rejection without any reason. I asked for feedback, but nothing was shared.
I spent over 3 hours on the test, and they didn't even bother telling me what did not work for them. I asked again, but received no answer from HR.
