I just had my first phone screen and don't know the result yet. Basically standard PMP answers are expected. Questions I was asked are project stages, project constraints (hinted by golden triangle), project closure and critical path. I frankly stated I am not familiar with PMP terms and will answer according to my work experience. After two questions I was told to give short answers so I am not optimistic to my result when PMP standard answers are expected. I learned from this forum so hopefully my sharing will help some who are interested in Google TPM job.

Direct onsite because I interviewed in the past and did well that time. From the time I sent my resume to interview day: 2 weeks. From interview day to offer over the phone: 2 weeks. The syllabus for the interviews is very clear and simple: 1) Dynamic Programming 2) Super recursion (permutation, combination,...2^n, m^n, n!...etc. type of program. (NP hard, NP programs) 3) Probability related programs 4) Graphs: BFS/DFS are usually enough 5) All basic data structures from Arrays/Lists to circular queues, BSTs, Hash tables, B-Trees, and Red-Black trees, and all basic algorithms like sorting, binary search, median,... 6) Problem solving ability at a level similar to TopCoder Division 1, 250 points. If you can consistently solve these, then you are almost sure to get in with 2-weeks brush up. 7) Review all old interview questions in Glassdoor to get a feel. If you can solve 95% of them at home (including coding them up quickly and testing them out in a debugger + editor setup), you are in good shape. 8) Practice coding--write often and write a lot. If you can think of a solution, you should be able to code it easily...without much thought. 9) Very good to have for design interview: distributed systems knowledge and practical experience. 10) Good understanding of basic discrete math, computer architecture, basic math. 11) Coursera courses and assignments give a lot of what you need to know. 12) Note that all the above except the first 2 are useful in "real life" programming too! Interview 1: Graph related question and super recursion Interview 2: Design discussion involving a distributed system with writes/reads going on at different sites in parallel. Interview 3: Array and Tree related questions Interview 4: Designing a simple class to do something. Not hard, but not easy either. You need to know basic data structures very well to consider different designs and trade-offs. Interview 5: Dynamic programming, Computer architecture and low level perf. enhancement question which requires knowledge of Trees, binary search, etc. At the end, I wasn't tired and rather enjoyed the discussions. I think the key was long term preparation and time spent doing topcoder for several years (on and off as I enjoy solving the problems). Conclusion: "It's not the best who win the race; it's the best prepared who win it."
