I applied through another source. The process took two weeks.
The interview experience with Sigma has been one of my best interview experiences. The team is very talented, extremely nice, and helpful. They made the process extremely stress-free. I got in touch through AngelList and had a 15-20 minute call with HR. They got back with a HackerRank test link, with more than enough time to complete the test.
Next was a phone screen with the CTO on CoderPad. He asked two questions and focused on code readability, quality, and correctness. Then they moved to the onsite, where I had three rounds with the CEO, CTO, and a founding engineer. All three were more of collaborative problem-solving and design sessions. I had another telephonic round focused on problem-solving after the onsite.
The questions ranged from graphs, parsing, and dynamic programming to distributed system design.
