I applied through a recruiter. The process took 4 weeks. I interviewed at Yahoo (Buffalo, NY) in May 2011
Interview
First phone screen, rapid fire round of unix shell commands by HR only, one word or one command answers. If cleared on-site or hiring location interview, mostly troubleshooting questions, just google basic networking questions like dhcp, tcp, uni/shell commands, and do you think you would be happy in this profile not very competitive, just want self-manage and smart spoken person. It was mass hiring - had stay in courtyard Marriott and then interview next morning in bigger Marriot. Don't know if it was planned this way or it was coincidental, had networking dinner, make most of it. This is where you can leave an impression. If you are looking for programming job, don't opt for this, you will never be happy.

Question 1
