I applied online. I interviewed at Fiserv (Nenagh) in Nov 2025
Interview
Seemed very straight forward. Nothing out of the ordinary as far as interview questions go. But I didn't receive either a positive or negative response after the interview, and that seemed slightly unusual.
I have never in my life seen a worse company who actively does their best to ensure they waste your time and have nothing to show for it.
I was reached out to almost a year ago about an SDE role. I was told there were going to be 2 interviews (technical and final). Those two turned into four with two "we're not sure if we're going to hire for this role". I went through a significant amount of stress and constant follow ups with no end in sight. For this one job alone I had to deal with multiple recruiters. Again, I have never seen such an egregious amount of effort put in to ensure my time and hopes of getting a job are wasted. Fiserv should be ashamed but I know they wont care because of this employer advantaged market right now.
Interview questions [1]
Question 1
Database locking, multithreading, and other concepts.
It was easy and smooth with total 3 rounds including technical, managerial and HR.
A panel of 2 were there in each of the first two rounds. Easy to crack the interview.
