If you are really free and don't have any work then you can go for the interview because doesn't matter whether you are cracked the interview or not they not gonna hire you anyway. I am telling you what happened to me. On 4-9-18 I went for the interview that was the weekday I took half day for the interview reached there before 9 because the mail you will get from the recruitment agency (in my case new era) they will force you to reach there at 8:30 am in the morning. Now they called around 30+ people on weekdays and you have to sit there for at-least an hour for your turn. There was only one technical round which goes around 20 mins in my case after that the HR said I cleared the interview I need to wait outside for the HOD round there were 3 more people with me we all 4 waiting outside and around 30 mins later the HR came and said HOD is in the meeting and he doesn't know when he will be free So either you all can decide when you can come tomorrow for the HOD round or we can communicate with the consultancy so we agreed for the consultancy thing and leaved there office. As soon I reached the office I get a call from the consultancy like I cleared the interview and will let me know when will be the next round I also got the mail and after 2 days the consultancy person called me and said my profile is on HOLD I mean on what basis I didn't even tell them my expectation yet. They are fraud same thing happened to my friend as well around a month ago I thought he might not cleared the interview but I was wrong. Please don't go there.
