Thomson Reuters Research Engineer interview questions

An HR call without video, standard questions about my reasons for applying, UK work permit status, and salary expectations. After that they introduced the hiring process, which would involve about 5 stages: a call with the head of HR, cultural/technical, technical, a take-home task to be completed within a week, another cultural. After that initial call, I was completely ghosted. It felt more like a data collection exercise, especially since they didn’t share a salary range when I asked, only said they’d inform me after gathering input from other candidates.

Online screening OA assesstment in hacker-rank. Fairly unexpected if you haven't given interviews before. Asks about https, ML, and REST APIs. Then if you are lucky, you get selected for an online interview where they ask you about a past project - very subjective and depends on whether they like you or not.
