Phone Interview. Recruiter could not tell me if its was discussion only with manager , or will be a technical interview with a Panel. There were 3 people (including manager). No Introductions from their side except their names. Seemed rude & unprofessional. Manager asked me to introduce my background . Once I was done, asked the team to ask questions. There were very specific product related questions down to program / Functions , flag variables level. Answered tons of the questions correctly, & for some I explained the approach not specific answer. Not sure if the interviewer was a contractor trying to save his job.. For someone with many many years in the industry, I have never seen such specific questioning. Seemed more like they were going thru motions to eliminate. Manager told me that recruiter will get in touch with me , although I doubt it.
