I was contacted by a member of their TAG group. It was mentioned that the interview was not an walk in and only few selected people would be there to try for the position. Big joke that was. Atleast hundreds were there for the few seats available. These people would mislead you with these statements.
All of that is still well and good. Now comes the exact bull part. Since they called so many people, they needed to screen a hefty number out before starting interviewing. They did so with an Amcat test. The position I was applying for was Java Microservices Springboot Developer and the test had so many sections on front end things like JS, JQuerry, Html, Angular, React, Reflux or something. There was also some NoSql section along with some concepts which are to be known by scrum masters(what the frikking heck will a developer do with knowledge of what a scrum master should know ?). And to top it off in experience column there was only 1-5 years option, meaning what 5 year exp fellow would have to answer, same 1 year would have to know and answer.
Aced out the java and persistence api questions but they were not enough to carry me to next round as number of irrelevant topic questions were far more. So I ended up wasting almost the entire saturday afternoon which I could have used to show up for some other interview. My mistake was I thought it'd be better to turn up for a interview for a company with a bigger name, and I was wrong. And its not just me, there were numerous others who also felt the same.
Advice to others would be to skip the company as they dont have a balanced interview process at all.
