Synopsys Software Developer interview questions

Phone call and online programming test involving Java Spring. Three meetings in person and a Java programming test onsite. Interviews were either informing me about the projects at Synopsys, or asking me about my previous work.

I had a brief phone interview and was asked to do a programming assignment afterwards. The assignment itself was fairly straightforward but quite lengthy. I spent ~5-6 hours on it and sent it to the recruiter. I got an email back saying that it would be looked at in the next few days and then never heard anything from Synopsys again. I sent multiple follow up emails to the recruiter and they all appear to have been completely ignored. If I’m asked to spend a significant chunk of time on working on an assignment then I’d expect to at least hear back from the company at some point instead of getting ghosted.
