I applied through college or university. The process took 3 months. I interviewed at Yahoo (United States)

Interview

2 phone interviews. First one was pretty basic, asked about general concepts like object oriented programming. Second one came about a month later. Interviewer asked me to write some code/pseudocode on collabedit using singly linked lists. Also asked about binary trees and how to find least common ancestor using linked lists. Finally asked go to Sunnyvale for onsite interview day. The interview day took place a month after the second phone interview. The job title "Technical Yahoo" is just a general title for a programmer at yahoo. There are many different programming departments. General presentation of the company is given in front of everyone. Lunch is served. Later, an employee picks you up to take you to a room for interview. They ask technical questions, ask you to write code/pseudocode on whiteboard, explain your code, optimize, etc etc. 3 individual employees have separate 1 hour interview sessions in total. About 1-2 weeks later, you will know if you got an offer or not through email.

I interviewed at Yahoo (Sunnyvale, CA)

Interview

I had two phone interviews, one with an engineer and one with the hiring manager. The first interviewer was pretty inexperienced; he quizzed me on OOP terms for the whole interview (What is an abstract class? What does the static keyword mean?). The second interview was much more enjoyable as the interviewer was more skilled. He asked me to implement a Page class and a Book class, and to use these to determine how many times a given word appeared in a Book. He then asked me to optimize my solution, which I did using a HashMap.

Interview

I dropped my resume in university career fair. And I was contacted quickly after that. I got two interviews, both phone screens.Interview Details – I submitted my resume through the job fair of my university. I got the email of the first interview after more than one month. For the first interview, I was asked some general questions about how to design a problem using different kinds of distributed and parallel tools, like Hadoop, Hadoop PIG, and MPI. I think the reason is that I have previous related projects. No online coding. For the second interview, the interviewer is a system architect. And we only discussed several question of Hadoop and HDFS. Also some general questions about OOP

Interview

Phone screen with Manager to get a idea of the fit and basic technical competence on projects. No coding questions on the phone. One site was a about 6 1:1 interviews, all coding on a whiteboard. Lunch with hiring manager wedges the day. What was annoying was I particularly stated I did NOT know PHP, but one interviewer just had a stick up his butt about requiring me to write PHP code to solve problems. I offered Python, C or Javascript solutions (my Java was rusty) but he wanted PHP. More annoying was he had like 1 year out of school experience, and ONLY knew PHP. Silly. The interviewer wasn't even on the team I was interviewing with and I got the job anyway, but just annoying someone focused on language specifics of a language clearly stated I had only briefly looked at.
