Rightpoint Senior Android Developer interview questions

Applied through a company HR recruiter. The process took 2 weeks. I interviewed at RightPoint in Dec 2021 Interview It included 2 rounds 1 technical discussion and 1 coding round with US team. I cleared all the technical round and HR verbally confirmed to release an offer letter but never heard back even after so many follow up they were asking me to wait. I waited till last and then joined other company. Entire recruitment process was useless for me.
