4 yoe as a software engineer, multiple places but not at a top company.
I interviewed at FB a year and a half ago and got to the onsite but didn't pass.

I took an Amazon coding screener recently and failed - so one area of improvement are with BSTs.

Do you have any study schedules, resources, and/or experiences you'd like to share?

Also, has anyone gone through the LeetCode FB product? Worth getting?
