I only had one interview with their recruiter/headhunter and there's three things to mention:
1. They don't leave enough time for one to ask questions, they were on the run after the miserable 30 minutes they booked.
2. After asking me to tell them about my background and expertise, they cut me in the middle to say that they had a question prepared for that, if I could save that for later and continue somewhere else (?!)
3. Instead of asking me some questions, they sent them directly on the chat.
Honestly speaking, this is one of the worst first interviews I've participated, for a manager position.
