Booking.com interview questions

pretty standard on paper, but in reality, ridiculously hard. I interviewed twice for this company, never made it to onsites, when I did multiple onsites for aws, meta, microsoft, palantir. Not being bitter, but I wonder who they manage to hire if they are more picky than more attractive companies. Also, I guess this is bad luck, but the interviewer I had had very poor communication skills with a poor mic and total lack of empathy/coaching, which made my interview even more painful.
