I have applied for different positions based on my interests and skills related to wireless systems. but i have received the first email in 2 days checking my interest in some position that I didn't apply for, but my profile is well suitable for it.

Phone screen then had an interview with the hiring manager. The hiring manger joined the interview 8 minutes late. The interviewer was polite but the conversation is a little awkward

The interviews were a part of friendly process. The interview were about getting to know you instead of asking silly "gotcha" questions. The hiring manager asked detailed questions about the experience listed in my resume. He wanted to know how I went about performing the tasks I listed in my professional experience section.
