Google Software Engineer(Internship) interview questions

first I got a link to solve 2 coding questions within 90min. nothing too complex, practice string manipulation and general data structures with emphasis on Hashmaps. Then got two phone interviews with 2 engineers. It took me a while to understand the questions asked by the engineers, they dont make it very clear to see if you ask the right questions.

Starts with a coding quiz/sample and progresses to two phone interviews where you code on a Google doc with two different Google employees. My first interviewer was 15 minutes late (which almost made me miss my second interview). His accent was thick and he kept changing what he wanted me to code. Second interview went a little better but neither of my interviewers were helpful like I had read on previous Glassdoor reviews. Instead of helping when I got stuck, my second interviewer laughed when I'd ask for clarification. Also my original recruiter never followed up with me. I had to email her asking for an update and then she called minutes later to tell me super bluntly that they were not moving forward with me. I was expecting more professionalism from Google.
