First had HR screening round which was straightforward , after that received assignment test based on frontend and backend which was quite simple. Got positive feedback on test after requested HR to review. Next round scheduled for technical paired programming interview with 2 members of their technical team, program was simple react code to accomplish small tasks. During test, solved all the problem statement given by their team. The same time interviewer seems like was not satisfied with solutions as the solutions looks different than he expected. In short, he was not getting the code solution even problem statement has been solved. Next day of interview, received auto generated email from the team that not moving forward with the application and there was no feedback attached to it. After spending 8 hours on test and a hour interview, they should send feedback saying what went wrong and what was expected, otherwise candidate might feel waste of time. Praising here to Recruiter for great communication and keeping updated (which looks better than how it was a year ago can be seen in the comments here).
