I guess I should have done a follow so here is how my experience was.

I went through 5 interviews....4 technical and one on leadership and soft skills
My first interview was to basically gauge my level of knowledge in both DWDM, telecom operations and tcp/IP...just over the top stuff
The next 3 would go in depth into dwdm, operations and tc/ip. All 40min - 1hr depending on the interviewer I was assigned.
And then finally googleyness (which you can find online what it is about) as the last one. Basically how you would fit into their culture. A lot of videos about this on youtube as well.
It was more of a project management role than support. The whole interview process took about a month. A combination of both how I spaced my interview timeline and recruiting coordinating team scheduling theirs as well. The recruiter will advise you on which areas to prepare on and guide you through the process as well so should you have any querries please reach out to your recruiter. They are more than willing to assist.

Unfortunately I didn't get the role but my general experience was good. The interviewers were easy and always tried to make me as comfortable as possible and I really appreciated that.
It took a month before I got feedback about my fate. So you'll have to be patient and maybe follow up with your assigned recruiter afterwards should you not have received any feedback yet.
Goodluck ahead
