I was contacted by a recruiter after seeing my profile on linked in. The process started off with 2 phone interviews - one with the hiring manager and another with his co-worker. 1st phone interview - Asked a lot of questions related to my resume. Questions on what I worked on in LTE protocol stack development. It was more of a screening round to see if my profile matched their requirements. The first interview went well and had a second one with the hiring manager's co-worker - He asked me a lot more questions about my previous work experience and domain knowledge on protocol stack development. The recruiter contacted me the next day and said they were happy with my phone interviews and would like to invite me for an onsite interview. The onsite interview consisted of 7 back-to-back interviews with all the team members and a senior manager. Questions were all related to LTE technology and my work experience. Every interviewer asked one or more coding question in C which had to be worked out on the white board. Questions were not very tough and if you had trouble finding a solution immediately(due to nerves), the interviewer would help you a bit and guide you towards a solution. Everything went smoothly but unfortunately I never received an offer.
