LinkedIn interview questions

Went through 3 interviews, first had phone interview and then was followed up by meeting with team members. There was no written test. Was very conversational. The interview process is much more difficult now.

I had my first phone interview with them. They seemed like nice poeple. But one of them was hired at linkedin a month before my interview and the other interviewer around 6 month before. I checked their background and they were almost new graduates from BS!! I have MS and couple of years of working experience. They asked me about my project and when I started talking about Weka algorithm and how I used it in my project, they were constantly asking what is WEKA?!! I was surprised that they didn't even know about that. Then they asked two questions. First was too simple, but they were trying to exaggerate it. I solved it with two different approaches. The second one was complicated but the issue was my internet connection got lost at the beginning of that and I couldn't resolve the connection issue so couldn't code it but provided the solution verbally and explained to them that I didn't at all expect internet connection issues. The interviewer said my verbal solution is correct. I was so mad at Comcast at that time, we switched to a faster service and it apparently became worst. around 2 weeks later I got an Email from recruiter that I wasn't the best match! Seriously, they didn't even give me a second chance even though they knew it wasn't my fault. Anyway, overall being judged by a person who was hired a month ago at Linkedin right after collage, I didn't expect much more than this.
