Cloud Lending Solutions interview questions

Repeated unwanted questions on Data Structure for a job profile in salesforce. Despite clearing two technical rounds and being asked to wait for an HR round, i was told HR wasnt sure and a new technical round was added in between. Which again was repeated irrelevant questions on data structures which were pretty annoying. please have your interviewee know something about the technology before allowing them to take an interview. Despite managing to give a good interview I didnt get any offer rolled out.

Everything was good. I went around 6 round of interview and I have cleared all the rounds. Even HR told me he will be sending offer letter with in 3 days. But these people are so irresponsible I tried to call him/her to know the update and even I sent mails also. But no update from their side. If you call them they will pick your call then suddenly they will cut the call also. So requesting you to guys please don't waste others time because for this interview I haven taken leave . And I wasted my whole day to going through all rounds of interview.
