Company give me one quiz round, one lengthy assignment after that 1 interview round conducted of 1 hour and 45 minutes. However, Company doesn't value the candidate's time and they did not respond to me. I have given my 3 weeks time in this whole process and after that, I didn't get confirmation regarding next round/reject/interview feedback from the company side.

This was for the Research Scientist - Deep Learning role. There was first an online test which had a 40% cutoff to qualify for the next round. Questions were based on statistics, probability, permutation and combinations, machine learning and deep learning. I qualified for the next round based on my score but they ghosted me and after 2 months of my asking them, they told me that they have moved on with other candidates. Bad HR Management.
