Long interview process with several steps. After a long time interviewing, they made an offer way below the advertised range.

Question 1
Shallow questions about database indexing and networking
I applied online. I interviewed at River in Jan 2026
Interview
Pretentious interviewing dynamics. The CEO conducts the initial screening calls himself, but lacks the interviewing skills to effectively evaluate candidates for the position he's hiring for. He questions Staff-level ICs using college-level topics, such as database indexing and TCP/IP. Do Staff engineers at River implement databases from scratch or internet protocols? This approach is likely to attract only overpaid juniors.
