Interview Preparation Tips

Interview preparation tips for other job seekers - Salary package might be overwhelming, but i suggest you not to apply for the company. I personally have given 2 rounds excellently but still got rejected as they've got their candidates by then. If you've limited positions why to invite 100s of folks for F2F(hyderabad) ?

No employee perks, bad company culture & no work life balance.

I asked interviewer to tell about company's culture & work life balance. Even interviewer has nothing to mention some good.

Pathetic thing is that interviewer didn't introduced themselves & asked randomly searched internet questions without proper knowledge.

If there is 0 star rating I would've given that.

Again I'm telling you don't even apply for the company, they lure you by saying you'll be working for morgan stanley or goldman sachs. Don't fall into that pit.
