Behavioral Technical Presentation
The interview process started with a recruiter call, followed by a meeting with the hiring manager. The final round involved giving a presentation about my previous work to a group of team members, which also included technical questions related to the job. It felt like they had already decided not to hire me, and I suspect some companies interview candidates just to maintain a facade of fairness in their hiring process.
