I was contacted by a recruiter from Google and had a first informal call. After that, I received a list of materials to prepare for the first phone interview. During the phone interview, I was asked to solve a coding/design problem. After passing that, I proceeded to an on-site interview with four similar types of interviews. Throughout the whole process, a recruiter was there to help me with any questions. Although I didn't get the job in the end, I learned a lot from the entire process and the feedback I received.

To design an optimal solution (in terms of memory and speed) to a coding problem, I was asked to use the right data structure and design an efficient solution, providing real code.
