Expedia SDE-2 — OA, DSA, problem-solving, LLD, HM behavioral

I recently got an interview opportunity at Expedia.
OA: medium-hard level question
R1: DSA round medium level questions on graph, maps, sets
R2: Problem solving question which is more focussed on algorithm than implementation
R3: LLD round/ LLD discussion standard question of LLD
R4: HM round, mostly on projects, behavioural questions, current company working method and all.

How many days does it take to get response from them??
