Nexient Quality Engineer interview questions

I did direct application through the company website. I got an email from the company recruiter the next day and she wants to schedule a phone interview. We scheduled the phone interview but unfortunately, she did not call me at the time scheduled. I contacted the recruiter and try to see the problem. She said "She is running late, will call in next 20 min" but I did not get the call again. I got the call the next day at an unscheduled time! During phone screening, we discussed the job detail, salary range, company, and my experience. After the phone interview, I got a HakerRank assignment and 2 hours In-Person interview schedule at the Ann Arbor office. I had a great time with interviewers at the In-Person interview. Both interviewers were very nice and professional. I really like them and the teams there. I believe they like me too because I got positive feedback from the company recruiter about the interview. After 3 days, the recruiter called me and said that they want to make an offer at X salary. Also, she said she will try to get approval for +3k . She explained the benefit and some information about the company. But the REAL story begins the next day. I got an email from the recruiter and she said she could get approval 10k below what she said. This is the first time I had this type of experience with company recruiters! When I try to learn why this happened I got a response said: “We have discussed that we have rated you as …. and for we can offer…”.I can understand if the company has a range for a certain level. But WHY YOU ARE REACH OUT CANDIDATE IF YOU ARE NOT FINALIZED EVERYTHING FROM YOUR SIDE!! I am disappointed.
