Applied online and then got an email about an interview a week later. We scheduled the call for the following week. I had a 30-minute Teams chat with HR. Then a couple of weeks passed and they asked me for a second interview, which was another 30-minute Teams discussion.

The process was long but fair. There were multiple interviews and questionnaires. They were polite and seemed well-prepared. The position was entirely in-person, and I wasn't very interested in the end due to the compensation and conditions.

A recruiter reached out on LinkedIn and suggested I apply. After applying, I was sent some questions to answer. Once I submitted my answers, I was scheduled for an interview with the Controller. There was some back-and-forth with the recruiter about scheduling the Teams invite, with initial invites being sent with incorrect times. Eventually, after some confusion, we settled on the correct time. I then had the interview with the Controller and another team member. The Controller was very direct and seemed unimpressed, while the other team member was pleasant. The next day, I received a generic email stating I wasn't selected, followed by a LinkedIn message from the recruiter relaying the Controller's feedback that I lacked experience and wasn't prepared, which I found unprofessional and insulting.
