They are sending a lot of invitations, the process is super long, but don't hire a lot. 1. Many Form3 recruiters talked to me (and my friends) on LinkedIn. They are sending a lot of invitions 2. One or two phone calls with the recruiter. They are nice, but their goal is just to have as many people as they can to lose their time on step 3. 3. Technical work that can take from 2 days to 2 weeks depending if you know the tech stack. Need to make a client in Go (GoLang) for a fake API they provide. Everything must be production read, by ready I mean as many unit/integration tests as it would have in production and shouldn't have a comment if you had to create a merge/pull request. If they don't like it, a simple email with a small bulleted list of things they would change. It took them two weeks to review my work. 4. Three interviews of 30 minutes (I didnt reach this step, but this is a summary from every other glassdoor posts): - Code review (questions/suggestions) and how would you add CI/CD - Questions on inter-microservices communication and networking (OSI model, internet suite, HTTP, HTTPS, HTTP Headers, HTTP/REST API, TCP, UDP, IP, SSL, TSL, ...) - Describe architecture and do a simulation of an on-call problem, need to troubleshoot, find the problem and solve it. You should find a service returning a 503 response code and you need to scale up the number of instances. I gave the interview difficulty very hard, because it is super long and they wont give you a change if you miss one simple thing.
