Frontend Software Developer Interview Experience - Toronto, Canada

Process
I applied through an employee referral. The process took 2 weeks.
- 30 min intro chat with recruiter
- 1 hour chat about FE concepts (explain React / Redux / Typescript concepts to a junior developer; all stuff from the core concepts docs)
- 3 hour take home assignment (30 minutes discussing it, 2 hours coding it, and 30 minutes discussing the solution). You basically have to parse 2 JSON files and compare data for "matches" and "mismatches" based on names, phone numbers, etc. that are in different formats (I used fuzzy matching).
There are 3 more steps after this, but I was rejected even though I mostly solved the problem.
