It went well, first round was screening. Next was a 30-minute manager round, where we talked about my resume. Then, there was a 1.5-hour live React project implementation - specifically, building tic-tac-toe. I was asked to explain the complete process step-by-step and also to coordinate with what the interviewer was asking for, focusing on that.

Behavioral Technical Coding System Design
Started with a recruiter call for prescreening. Then another recruiter set up an initial interview with the Hiring Manager, which was non-technical. After that, there were multiple rounds: Interview 1 focused on daily tasks, handling unexpected situations, and team fit. If successful, I then interviewed with a senior developer, project manager, and director in separate rounds. Interview 2/3/4 involved coding tests and system design/architecture questions. The overall goal was to understand my perspective on projects. All interviews were great, and the interviewers were helpful in clarifying questions.

Behavioral Technical
It started with an HR call, then I had another interview with HR. After that, I interviewed with the manager. The manager seemed to think I was a good fit and had good skills. They said they would send me a python transformation test. Four days later, I got an email saying they weren't moving forward with my application. I think they might lack experience and good communication. I felt like my time was wasted. I emailed them to ask why, and HR called me on her personal number (super unprofessional!) and just said 'we cannot' before hanging up.

Technical Coding System Design Behavioral
The recruiting team reached out to me for this role. The interview process felt easy, and even though I passed all the stages, I got rejected. When I asked HR for feedback, they ghosted me. The hiring manager mentioned he likes the company because the founders were previous IDF soldiers. This struck me as a red flag because I don't see the connection to a tech company, and at the time, the IDF were committing genocide, so it felt like you'd have to support that to join.
