Netcore Assistant Manager- Service Management interview questions

Had applying over career section. got a call in a week from Hr. Had telephonic round first, which went quite good. and was asked to come to the officee for f2f round. 1. Went there had f2f 1st round - simple question on current role and how amny customer do i handle etc. (same person had actually took my telephonic round) 2. he asked to wait for 2nd round with sales head. who was out for lunch. after waiting for 2 hrs i was told sales head is not available hence they will call me back arranging next round. (could n't he had check his availability before calling me and fixing the meeting. 3 weeks later i actually drop a reminder mail and than was called next day. 3. A sales manager (not the original person as i knew his name) came with my CV and kept asking me my targets (in monetary terms) i told him my role is not in sales but he couldn't understand. 4. waited for 1 hr, after that the guuy who took my very first came and told me they will arrange 3rd round. I actually asked him for which role they were interviewing as i was feeling may the last interview guy was thinking i was for sales job. SURPRISE it was still for service manager. 5. waited till sales head round.. normal round he was just busy with mobile whole time. 6. last round with HR routine HR questions. expected salary etc/ asked for 35%+ hike. was told its too high i agreed to negotiate but nothing below 30%. even though i was least interested in this company by now. got a call next day i was offered 20% hike which i refused.
