I applied through a recruiter and the process took a day - interviewed at Yahoo in September 2010.

Interview Details The interview process was very straightforward and simple. The first step was the telephonic round. I was interviewed by 2 people over the phone. This was a test of basic technical skills.

After clearing this round, I was contacted by the recruiter who arranged for me to come down to Bangalore for 1:1 interviews.

In Bangalore, I went through 3 interview rounds from 10am to 4pm, with a break for lunch. Within a couple of days, I was contacted with an offer, which I accepted.

I applied through a recruiter and the process took 1 week - interviewed at Yahoo in July 2011.

Interview Details Attended the interview today!!!
Knew in advance that for them Experience level does not matter.
So prepared on data structure and algorithms for a week.

Initial round Phone interview(30 min) :-
Asked basic details about my work, then suddenly datastructure questions.

1) Find median from continuously changing stream of data.
2) Find 2nd maximum in array.
3) Find nth largest in Array.

-------------

Called for f2f discussion.
All 3 technical and one hiring manager rounds consisted of only data structures.

No one asked anything in Java. Though I was called as Java requirement.
Dont know why so much concentration on data structures only.

Also, I feel my skills were not matching, as they wanted someone who has worked on PHP,Perl.

Honestly, I was not expecting negative reply but I guess my 2nd technical round and skills impacted my interview.

At the end I feel that if you want to go to yahoo, then study like a fresher preparing for your first job. Experience level doesn't matter.

Interview Question – 1) Write merge function to merge 2 arrays into single array.
2) Find the length of linked list loop.
3) How to get the values of two elements from array whose sum is N.

2nd round :
1) Get nth largest/smallest from BST.
2) How will you remove duplicate paragraph from big file.
    Told hashmap, asked me to write hashcode :-(
3) Perform merge of multiple arrays. (k way merge)
    Thought for sometime, but could not tell. :-(

3rd round :
1) Middle of linked list
2) sum in binary search tree
3) Some unix questions.
4) How will u design Google maps or yahoo maps.

4th Round :
Puzzle on 25 horses.

I applied through a recruiter and the process took a day - interviewed at Yahoo in April 2011.

Interview Details It took whole day to complete the process. Surprised by the kind of people and kind of technical questions asked. Probably I had over expectations. There is no focus on potential, thought process and problem sloving skills but just very syntax and JCP kind of questions. There is no intelligence in the questions so very disappointed. Lots of API related questions which no software engineer need to by heart. Looks like Yahoo standard has been going down.

I applied through a recruiter and the process took 2 weeks - interviewed at Yahoo in May 2013.

Interview Details There are two phone interviews before the onsite interviews. I made to the second phone interview. The goal of the first interview seemed to mainly be about getting a good feel for the candidate. The interviewer asked me about past projects I had worked on and any problems that I had to overcome. The second phone interview was a technical test. He asked me technical questions, many of which I had found online from past candidates. The twist was how well you knew the subject, and not necessarily whether or not you got the correct answer. This interviewer's tactic was to continuously ask me "how can you make that solution better" after each question. He told me I got most answers correct, yet I stumbled each time he asked me to find a better solution. The stumbling, I feel, kept me from the onsite interviews.

Interview Question – How can you tell if a linked list is circular (goes on forever because it connects to a previous node)?   View Answer
