Overall a waste of time. Stage 1. Phone Call with Talent Acquisition Partner (60 mins), the interviewer was fantastic, Stage 2. Technical Interview with 1 Senior Architect and 1 Senior Frontend Developer (60 mins), where I was greeted by 2 very hostile people. We talked about my experience, achievements within my current role, a *ton* of technical questions revolving around React, code bundling, transpilation, and APIs (almost like an interrogation). There were a few ambiguous questions such as (literally) "How would you build a React app" and "How would you convert JavaScript to TypeScript" with virtually no feedback as you answer the question. When asked if they were satisfied with my question at the end, the answer was simply "yes". Having successfully answered every single technical question thrown at me, by the end of the interview it was clear that the Senior Frontend Developer felt threatened by me whilst the Senior Architect was very excited. A day later I received a rejection e-mail claiming my answers were not in-depth enough. Yeah right.

First interview with HR around 30' minutes, then an initial tech call with a couple of engineers 1 hour, then a home exercise in React in a week, then a second call with other two engineers 1 hour and the final offer
