Informatica Senior QA Engineer interview questions

Hiring Process include 1st telephonic discussion , taken by product manager .It was normal discussion about all sort topics i know . After that they called me for F2F discussion , it was decided between 11-3 PM but it extended to 11-5 PM Include 4 round technical discussions , questions related to java , puzzles were asked . Some of automation testing questions were also asked . After having day long exhausting interview they told me they will get back to me in a day or 2 . But after 2 days when i called they dint give any status and also no feedback mail saying if its negative . This is really bad on HR side , they bug candidates until they come for interview and after process atleast they should be courteous to give them feedback .

after phone screen, got an onsite invite. They don't look at resume that much, some ppl will be interested in your past projects but they only allow to talk a little bit, <5 minutes, and have to jump to coding/technical questions. This is almost my first onsite after years of working. I forgot those algorithm questions in school. so I did not do good with bst related questions. No call/email after the onsite.
