I was given only 4 hours notice of a task to complete, suprised by upper management in the interview and that it was 1hr rather than 30 mins. the task in interview didn't match the brief properly, and I felt humiliated in the first half of the interview by obscure questioning.

2 rounds (first with team manager and second with operation manager), Always be sure to research the company and role you're applying for to understand their specific interview procedures and expectations.
