Interview preparation tips for other job seekers - Prepare yourselves to get the call back after the scheduled interviews after a month or so if you are selected.

If you get the offer letter, please do not join this company.

Not very considerate people, though the policies are there. No WLB, politics, poor product and project management. Architects know the stuff but they don't have the documents about the products, no KT.

Again please seriously take this advice, if you get one offer, please do not join the company.
