I recently interviewed with Sell.do for a developer role and it was quite an energizing process. The interviewers were very technical, asked me about real-world problems, and discussed how Sell.do product works, not just abstract algorithmic questions. They seemed genuinely interested in how I think and how I’d contribute. They asked me SQL queries, DSA and Projects There were total of 4 rounds of Interview
