+1 to this - I’ve had countless interviews for SRE positions that were pure leetcode. If I were applying for SRE roles today, I would take it as a signal and just stop the interview and leave. Leetcode interviews are a big part of the reason why I left my career in tech. I’ve built infrastructures that handled 30,000 requests per second at dozens of datacenters - never once had to implement my own graph search.
