Initial call with technical recruiter and then some basic networking questions which they would read from their internal website portal. They look for some words from your answers. They will tell its the formality and would not be shared with hiring manager mostly. Worst part is they are not technical, hence the questions they read doesn't have any context, or they don't know it. Upto you to bring context to it. After technical screening, a networking protocols round(almost 45 mins), then coding screening(shared desktop) online, then onsite interview(5-6 rounds).
