Worst experience... I wasted an entire month going through a total of 5 rounds:
1-Online assessment
2- L1 technical -Online interview
3- L2 technical -Asked to come to the office but ended up doing an online interview
4- Another technical interview (due to miscommunication with HR)
5- MR round - discussion about salary
After all these rounds, their audit revealed that I had actually failed in the first round itself. A complete waste of time and energy.
