I applied through a recruiter. The process took 2 days. I interviewed at SoloLearn (Porto, Oporto) in Mar 2022
Interview
Slow and painful.
Very, very long interview dozen of contents, with quite subjective answers.
Vague questions like: " How would you design instagram app..." or "how would you modularize a project..."
Notice a little lack of respect of others experiences, as if questions only have one valid answer an all others perspectives are wrong.
The process is aiming for your mistakes only, like it used to be on the good old days.
Interview questions [1]
Question 1
Design patterns, memory management, SOLID (in depth, as they call..), network, time complexity, space complexity, location services, TDD, Threading, deadlock, git usage, value x reference.
Video call with 2 other iOS engineers. Questions were focused on computer science and not iOS development. Questions were also basic in nature but requiring drawn out answers. Some answers were verbal, others were on a virtual whiteboard. The efficiency of each answer had to be explained and a more optimised solution had to be presented if it existed.
