Date: May/June 2019

Phone interview:

• work experience
• behavior questions
• https://leetcode.com/problems/group-anagrams

Totally 4 rounds for onsite interviews:

Round 1:

• https://leetcode.com/problems/search-in-rotated-sorted-array
• https://leetcode.com/problems/search-in-rotated-sorted-array-ii
• OOD - Design a calendar

Round 2:

• similar with https://leetcode.com/problems/find-and-replace-in-string The difference is: we need to replace ALL the strings in the given input string.
• talk about work experience, projects and the system design related topics (LB Cache API design)

Round 3:

• https://leetcode.com/problems/word-ladder but with a complex description. Same idea, and process.

Round 4:

• Merge two Sorted Arrays
• how to implement cache for a system - open ended, just ask the requirements and what we need for the system. Then implement the code.

For each round, there were 1-3 behavior questions and talked about work experience for 10-15 minutes. the rest of time for technical.

some suggestions:

• use libs to save time
• skip some util methods and focus on the main logic and process for the problem
• one hour for say hello + introduce yourself + BQ + 1-2 technical Qs is really tight
• so make the conversation short and concise. if interviewer is interested in the details, then talk more
