HR interviewer was quite friendly although didn't know much about the exact responsibilities of the person they were looking for. Then they sent a task which I completed easily. I waited for 3 weeks and didn't get any feedback and decided to contact them myself and ask for an update. The HR girl wrote me that the headcount was filled by an internal transfer. Well, even in such cases, I should have been contacted and informed accordingly.

Heard back from recruiter after applying for the job on Linkedin and had a great phone interview with him. At the end of the interview, he said he would discuss with hiring team and get back to me. A few days later I received a canned email response saying thank you for applying but we are moving on to other candidates, the same canned response you would get when you apply and are rejected right away.
