Full Experience
I had my technical screening for a Senior Software Engineer position at LinkedIn. The interview began with a 20-minute discussion where the interviewer asked me several questions about my current job and projects. Following that, I was presented with two coding questions. Both problems were quite familiar to me, and I was able to approach them confidently. I am now waiting to hear back about the outcome of this round.
