Fiserv Sr. Software Engineer interview questions

Had two virtual interviews: HR followed by a technical. The HR interview was the standard process of getting your career background, why you're interested in the role, etc. Essentially finding out if you're a culture fit. The technical interview was virtual with you being interviewed by 4 engineers. The questions covered high level concepts of technology and processes you have used on projects listed on your resume. The problem was that one of the interviewers dominated the interview, consistently interrupting both me while responding, and their fellow interviewers to ask their own questions (looking at the faces for some of the interviewers, they were surprised at this occurring). This felt very unprofessional on that person and ruined an otherwise fine interview session. After that, I was ghosted by the talent acquisition manager for the company for weeks. This was after they had insisted they needed to move quickly to hire someone and how responsive they had been before the technical interview. At least give the courtesy of an email rejection to candidates.

I interviewed for a role and unfortunately had a disappointing experience. The panel came across as rigid and dismissive, especially the lead interviewer who lacked basic courtesy and professionalism. The overall tone felt like an interrogation, not a collaborative or respectful technical discussion. What stood out most was how outdated their technology stack and release processes were — reminiscent of setups I worked with nearly a decade ago. Their questions focused heavily on specific older tools, with little interest in broader experience or modern practices. At one point, I was asked how to run a command in a tool I haven’t used in years, despite explaining I’ve been working with more current frameworks and CI/CD systems. It felt like they were looking for someone to match their existing setup exactly, rather than someone who could improve or modernize it. I ultimately declined the role. Since then, I’ve had great conversations with other companies that value adaptability, professionalism, and forward-thinking engineering. The contrast was clear. Let this be a reminder: interviews are a two-way process. You're a professional evaluating whether a team, company, and role are helping you grow. Respect your value. Choose where you invest your time wisely.
