Epsilon Senior Client Integration Engineer interview questions

Api integrations, SQL, few questions about role and previous experience in your present company in round 1 and round 2 &3 will be general questions. They tell all three rounds are technical but the us team are non tech guys who interview for tech role but they lack technical knowledge. Please don’t waster or keep hopes if they delay more than a week they say the interview feedback takes 24 hrs to reflect in portal I’m not sure how much old portal they are using you need to constantly keep following up hr they barely respond and they took almost a month to do 3 rounds and again a week later they say we will get back to you and say we found a better candidates honestly please don’t waste your time if the same pattern repeats
