Contacted by an in-house recruiter for a SWE Ugrad role. Went through several informational calls. The interview process involved the following layers:

• Online coding assessment
• Phone/Hangouts interview
• On-site for 4 interviews with current SWEs (Graduate roles will have 5 interviews).

Google is incredibly upfront about what it wants from applicants. You need to know your algorithms, data structures, and dynamic programming to make it through the interview process. The entire process was very relaxed and informative. During the on-site, it felt more like an educational/professional experience than a high-stress interview.

Given three operations (UPDATE a character, DELETE a character, and ADD a character) and a string, find the minimum number of operations required to convert the string to a palindrome.
