Lengthy but varied rounds you will have HR round,Skills, Problem solver, Coding Practice, Team Fit and then maybe another final Panel round HR persons are internal so they will support you throughout the process and its in their benefit to hire

Recruiter reached out via linkedin. Fast tracked interview with Reporting head and team mates for tech and culture fit. My current salary was discussed beforehand and they proceeded with interviews. Setup a meeting about salary expectations and the offer half of current salary. I politely informed them to improve it and not necessarily asking them to match it and I consider. They then came back telling me they decided to hire internal as the expectation about salary ranges is way out of range.
