Make sure to explain what the interview will involve beforehand. I was expecting a code-a-long SQL exercise, as is standard in the industry, and instead shared their screen showing a SQL question inside a spreadsheet, which did not give a good impression of Gopuff as a "tech" company. I was then asked questions that I was completely unprepared for and were unrelated to my actual work experience, meaning I wasn't able to demonstrate my actual, real-life skillset. The interviewer was rude and unprofessional, starting the interview by criticizing the company I currently work for, then going on to ask questions about my current company's strategy which I could obviously not disclose and clearly a tactic to steal ideas. To top it off, even after taking time to do two rounds of interviews, the recruiter gave me no feedback and sent an automated rejection email instead.
