I started with a recruiter from India reaching out and then connecting me to a recruiter based in Cambridge.They described the Job well and scheduled me for the first round of interviews. The final round of interviews with the panel went well as well where they tried to understand depth of understanding of CDNs and candidate's thinking ability. What bothered me however was the followup after the Interview where I was told that they are interviewing some internal candidates after my interview. If you had to interview internal candidates after interviewing externally, its a clear waste of time for the external candidate. I would suggest you interview internally first and find the right candidates before even posting the job externally.
