Devsinc interview questions

It was an HR screening, followed by 2 technical interviews and a behavioural interview. The HR screening is straight forward. In technical interviews they start with OOP, then DSA including problem solving (on paper, no code needed), then DB.

got called for the first round after the hr screening, just some basic questions like AWS, AI, ML domain specific questions. the worst thing is that after putting me through 3 rounds, they hired an internal resource. why couldn't they hire one before putting me through all those rounds of constant rubbing.
