Google Software Engineer Internship interview questions

The interview goes on many processes starting with resume review then to a technical interview then online one, for me I passed the technical interview and I didn't notice the online one on one .

it was tough i got asked only 2 dsa problems which were quite tough and the topics were graph and string. the string question was of medium level and was doable but the graph one was really hard i tried some approaches but still wasnt able to solve it completely but still i got the internship opportunity.
