The quickest hiring process in my professional experience.
On Friday I had I call with HR, at the start of the next week a technical one, on Thursday - a final call with COO and 15 minutes after that call - an offer.
So, if you want to be the slowest person in the process - it might be a good choice :)
+ Fast processes, responses, no ghosting at any stage
+ Personalised technical interview questions, no questions that are not relevant to the position
+ Individual approach, possibility of exceptions to the rules for the comfort of employees (not really related to the interview, but these points are discussed there)
- Personally, I didn't have enough time to communicate with my immediate manager or C-level manager during the process, but I think the speed was worth it
