Preguntas de entrevista para el puesto de Backend Developer - Java en TranServ

Interview process was simple but ended with worthless experience. Got a interview call through a consultancy and written test was schedules on Saturday. Written test was simple with most of the question repeated from their previous test. Cleared the test and 2 technical rounds were taken later. On clearing those, an HR with formal discussion about why want to switch, expected ctc, notice period, etc. the HR manager promised to call me on Monday but they never contacted, nor she picked call from me or the consultancy. If they were not in mood of hiring, they should not have wasted time and efforts of those many candidates if time doesn't matter much for them.
