Easy Negative Portugal

I made it through all the stages and felt like I was moving forward, and then I was told they didn’t have an opening yet. They asked me to wait until the next year and see if a position opened up.

What bothered me wasn’t just the delay—it was the feeling that the process was letting people believe things were real when the hiring reality hadn’t caught up. I left thinking they should not draw candidates through interviews if they can’t hire them, because it wastes a lot of time and energy.

Average Neutral Porto, Oporto

My process started with a recruiter call, and right after that I had a more technical conversation. In the technical screen, I was asked about creating an encryption password algorithm, but the whole thing was hard to follow because the audio was bad and the format felt messy.

The recruiter experience also left a sour taste. The person I spoke with was late to the call even though I joined early, and within minutes they were already questioning whether my salary would fit without really knowing my details. After that, the tone shifted into something like they’d decided I wasn’t a match before digging deeper—questions about whether I was applying elsewhere, plus comments implying I was worried for saying I wasn’t desperate to leave my current job.
