The interviewer was disinterested and sarcastic. She ended up contemptuously questioning our back-end security protocols for 20+ minutes. These in fact are very strict. At the end, the interviewer gave curt two-sentence responses to my questions. I did make two factual mistakes under her sarcastic questioning; however, she made a mistake as well (contemptuously implying that encrypting API keys is stupid).

Easy algorithm question, casual talks. Everyone is a Senior Software Engineer but I did not see any senior. Teams are splitted by business streams and composed by mnay externals, and stack in Java and Nest.js. You will have a couple of rounds.
