Google Google Engineering Practicum interview questions

Two 45 minute technical interviews over the phone. Both questions had to do with 2d arrays! This was my first technical interview experience and it didn't go as well as I planned but a huge learning experience for me. Emailed me a week after the interviews notifying me I wasn't going to continue.

There were 2 back to back phone interviews. My first interviewer had very poor phone signal and I had to ask him like 3 times to repeat what he was saying for each question. The second one was fine from this point of view, but the interviewer seemed very bored and not interested.
