Interview Preparation Tips
PS:- I cleared the Technical round and then they scheduled the Managerial +HR round the very next day, without discussing the time with me. I asked them to reschedule, because of my unavailability. They rescheduled on the same day as per my request. I failed to attend at rescheduled time because of my Project work and I informed them in advanced. I also sent an apology mail to recruiting HR but they didn't care. So, manage your time well, if you respect the ethics(I could have lied to my current company, like power cut or some network issue, to get some time to attend the interview).
