Interview Details

Had three onsite interviews, which were easy to medium in difficulty. The interviewers did not seem that well prepared but everyone was in general friendly and competent.
However, HR is a mess. It took them over three months from the day of my onsite interview to send me an actual offer letter, which is completely unacceptable. Furthermore they didn't communicate with me at all--they'd tell me they would get back to me that week and then not respond for another 2-3 weeks. And you can bet they won't reimburse you for your onsite interview.
I had a good onsite interview experience and might even have considered Yahoo had their recruiting team not been so awful. It really reflects badly on the rest of the company.

    I applied through a recruiter. The process took 3 weeksinterviewed at Yahoo in December 2014.

    Interview Details

    Having read through the reviews on glassdoor I wasn't expecting a smooth process either but since I am a local candidate I didn't have to go through the hassle of going through the travel/stay reimbursements etc. The reviews were true to the core that the recruitment process is a clear indication of the complete chaos in the company. I was invited for an onsite, after clearing the initial phone screen which was fairly a simpler algorithmic challenge. Just revisit your algorithms and data structures especially search, sort, list, trees, graphs, string manipulations etc. An advice to candidates is to not to over do the preparation as they come with a mind set expecting 'the' answer they were looking for and even if you out smart them with an efficient solution it's still frowned upon (which is rather untrue for most companies in the silicon valley).
    The onsite interviews were pathetic, with some interviewers jumping straight onto white-board coding without even a formal introduction. The questions ranged from generating random numbers between 1 and N given a function which returns 0 or 1 with equal probability (binary to decimal!), ways to provide contradicting assignment statements from a list of string assignments of the form ['a=b', 'c=d', 'd=b'] ['a!=d'] etc, string anagram matching, binary search trees. The engineers seemed technically sound/professional and will indeed provide you enough hints in case you run into troubled waters.

    I applied through a recruiter – interviewed at Yahoo in December 2014.

    Interview Details

    Recruiter was really nice she contacted me and i had one phone interview where I had to find out the last node of the tree(BFS) and search an element via binary search with one extra condition

    Flew over to Sunnyvale excellent people, great campus, streamlined process. had 5 interviews along with lunch (big cafeteria). it was for mail/communications team
    1. parking design, using hash table check if two strings are Anagram
    2. given a string find whether it matches on a big string or not
    3. flattening and un-flattening a binary search tree
    4. one more logical or data structure question using iteration ( result should be in n). i think everybody in the room knows the celebrity but celebrity doesn't know anybody. how many celebrities in the room)
    5. storing a ton of sets with Transitive relation in tables so that look up is very easy.

    Funny recruiter never contacted me again , i think i messed up two of the interviews.

    Folks were very neat in their approach and very efficient, one of the easiest interviews I ever had.
    All the interviewers were really good
    Still cheers for the opportunity.
