It was the worst interview I've already made.
The interviews looked to not be very prepared to apply it. They made a lot of strange questions, and the feedback they gave it was I'm middle level. I'm right about my seniority, but I learned plenty of things doing this interview. For example, the whiteboard, isn't a whiteboard, talking about technology or other things, it's a tech "challenge" to reorder some data in 3 CSVs files.
All tech interviews looked unhappy doing this job, so I started to think about the position.
A piece of advice, don't apply to a tech position. You'll lose your time too.
