Recruiter call (Initially, the recruiter only mentioned there would be two virtual on-sites, skipping the online assessment after I mentioned a previous negative experience.)

• Onsite #1: Data Structures/Coding (For questions, refer to other posts; they haven't changed.)
• Onsite #2: Concurrent Programming (Coding)

After passing these, the recruiter revealed three more on-site interviews and asked for my availability.

• Onsite #3: System Design (more of program design, not typical system design questions; didn't feel appropriate for a senior-level engineer.)
• Onsite #4: Data Structures/Coding
• Onsite #5: Interview with the Team Manager

All the people I met during the interviews were polite and humble. Technical interviews were mostly conducted by junior engineers.

The recruiter called two days later with a "No Hire" result, mentioning that feedback was positive but they were not hiring. Someone here had previously mentioned that they are not actively hiring but only let their junior engineers conduct interviews; my experience aligned with this. Additionally, none of the questions were new; almost everything had been shared in previous interview experiences.
