I was contacted by a recruiter on LinkedIn last October. Because I was considering quitting my PhD program, I pinged back. After that, we had three rounds of phone interviews. In January, the manager decided to move forward with an offer. I was ready to go there. However, in February, they decided to give me an extra onsite. I was surprised. Because Yahoo was my only offer at that time, I prepared my coding interview in a hurry. I performed badly in the onsite interview and planned to move on. So I prepared for another month for some exciting startups.

I was able to get an offer from Yahoo at the end of March, but the processing took so long that I received more offers from elsewhere. At that time, I was no longer interested in Yahoo, so I just wrote back a thank-you letter and let it go.
