Google Senior Software Developer Engineer interview questions

Dopo uno screening telefonico con una domanda di coding relativamente semplice (livello medio su leetcode), sono stato invitato per 4 coding interview e una di system design on-site. Le coding interview vertevano su problem solving e strutture dati e si son svolte alla lavagna.

Recruiter sent out numerous interview guides to review before the interview that repeatedly said 'talk out loud'. Interviewers asked questions that had pretty obvious answers so I explained all the more obvious but less optimal solutions before touching on the optimal one. The interviewers spent a lot of time asking about why those weren't optimal and apparently reported this as if I had to be guided to a solution. For what may be the first time ever, I got interview feedback saying I got to the optimal solution but it took some guiding. In summary, I did what the interview prep asked me to do, explain my thought process. This was perceived as if I kept taking the wrong path to the solution.
