Interview preparation tips for other job seekers - I would suggest not to take interview or join this company . They already have some people who they want to take and they just take some rounds of you and even if it goes extremely good they wont contact you back . Work here is also not good they tell as developer and will make you do devops writing yml files . This is what I heard from people inside . Even if you get this offer don't consider as first choice . This is my advice to people who are looking to apply here
