Average Negative Singapore

My interviews themselves were fine from a technical standpoint—during the loop I was told I was doing well and that the conversations went okay. But the process after that fell apart because HR was completely unresponsive.

I kept emailing people in the HR part of the interview loop after being told I was progressing. Over roughly five weeks, I didn’t get any replies back at all, despite following up multiple times. The whole time, I had the sense that the interview wasn’t the problem, but communication and decision-making follow-through were.

Average Positive Dublin, Dublin

My interview was pretty smooth and focused mainly on testing technical knowledge and coding ability. The interviewer was clear about the problem and kept everything within the allotted time, so there wasn’t a lot of uncertainty about what they wanted.

They used a coding setup that felt like it was built for speed—compilation and code completion worked well across multiple languages, and the tool itself made it easier to stay in the flow while writing and adjusting code.
