When recruiter called me about interview, he told it is just one round interview. So I went there to attend interview, they have taken two rounds of interview. First round of interview person was very good and he had good knowledge also compare to their manager. He had taken my interview and I answered almost except pivot table in SQL(I didn't know we can use PIVOT in SQL also, now I know and I can do it) . Then he asked ok you don't know pivot but if I want you do it how you will start, I told I will take help from Google and YouTube. He impressed he told exactly at least we should have learning attitude etc. So first round done now second round managerial round, she came and asked one non-sence question. Something like that Var a =9; .. .. .. .. .. .. .. .. a="mohan"; console.WriteLine(a); I told it will give compile time exception because var is type safe. She did argue like anything how you can say etc. That's why I told manager doesn't know (I don't know how she is manager) even first person senior software engineer having good knowledge. So finally I got response from recruiter sorry mohan you have not qualified. I was thinking to tell him directly that your manager only doesn't know then thought leave it. So this is my bad experience with JDA software.

During Interview process if you are making a switch rather campus placement it would be not much difficult and easy leetcode questions, Basic and foundations of OOPS, system design will suffice.
