I received a coding interview invitation for Google Singapore last week and completed the 60-minute, two-question coding challenge today.

The exam was quite difficult and required a very quick grasp of the questions' intent and dynamic programming knowledge. I've participated in over five coding interviews at Peak6, Amazon, and other companies, but Google's was definitely the most challenging, both due to the time crunch and the difficulty of the problems.

Good luck to all other candidates! I probably don't have the slightest chance at this position, but I wish you all the best.
