It was optimal but not the best. I got a response later than usual. But overall still a nice experience. The main problem was my visa I think, I think I did fine otherwise.

1 phone screen with networking related question and python coding, then 6 interviews onsite. Applied online, within a couple of days a recruited contacted. Scheduled a phone screen which lasted for 1.5 hours. Started with few behavioral questions like tell me about a time when you had a conflict with team etc., then asked networking concept questions related to ospf and bgp. Then two coding questions in python. After 2-3 days got an update from the recruiter for onsite interviews in Seattle. There were 5 rounds of interviews: 1- Coding, object oriented based, designing and coding a subscriber management system. 2- Networking concepts 3- Behavioral interview 4- Interview with hiring manager 5- Design related interview After 2-3 days the recruiter replied with an offer. Reason for declining: 1. Insultingly low salary. I mean it can be good for freshers, but not for someone with 4 years of work exp. Did not like manager's attitude, he was presenting the bogus work of network operations as if they were building a space-rocket. Initially I thought it would be software development into networking domain, but its totally operation work (dont kill your career) Through internal sources came to know that the team is always heavily loaded, on-call support also sucks, no work life balance, unsatisfied customers always standing on head.
