Chill interview process, 2-3 rounds talking to principal engineer for that team and recruiters, sometimes people have to talk to PMs too. Very friendly and conversational interview and felt like the guy had a genuine interest in getting to know me as a person and for my skills.

A 30-minute call with a recruiter, then a final panel interview with two senior data engineers. The first one was more behavioral and experience I have. The panel interview was very technical about my resume and a SQL problem to finish.

The interview process at Fiserv typically starts with an online application and resume screening, followed by a coding assessment with easy-to-medium problems on topics like arrays, hash maps, and strings. If you pass, you move to one or two technical interviews where you solve problems and explain your thinking, along with some behavioral questions about teamwork and past projects. The process usually ends with a final behavioral or hiring manager round, focusing on fit and communication skills.
