Applied to a senior SWE role at Samsung Research America, went through the full loop in late spring. Here's what I actually experienced.
Recruiter screen was standard, 20 minutes, mostly verifying background and timeline. Then a technical phone screen with a coding problem on HackerRank, medium difficulty, two problems in 60 minutes. Not trivial but nothing you shouldn't see if you've done a couple months of LC prep.
Onsite was four rounds back to back on one day, all virtual. One round was pure DSA. One was system design, my prompt was something like "design a notification system for a mobile platform at scale" which felt very on-brand. One was a behavioral round with a senior manager, heavily focused on how I'd handled ambiguity and disagreement with leadership. The fourth was a domain round with a principal engineer, more of a whiteboard discussion about tradeoffs in distributed caching.
The thing that actually surprised me: the behavioral round was weighted more than I expected. My interviewer wrote notes furiously every time I described a cross-team conflict situation. Coming from FAANG where system design usually dominates senior calibration, I had to recalibrate mid-loop.
Result: offer, L6 equivalent. Timeline from app to offer was about 7 weeks total. Slower than my FAANG memory but not painful.
