I applied through a recruiter. The process took 3 weeks.

Standard interview stages: recruiter, tech screen, and a 4-session onsite.

After a brief recruiter screen, I had a CoderPad technical screen. The interviewer seemed arrogant and unresponsive, and was very unwilling to work with me on understanding the question. Although I did manage to parse out the requirements for an unusual problem case and deliver a working solution without assistance, I was dropped after this stage.

Build a binary parser tree given an array of tokens where tokens have a type and depending on that type may have a left/right child to hold primitive values.
