Poshmark Software Development Engineer In Test interview questions

Really long process, 1st step would be from hackerrank question, they give you 6 hours to solve the problem and submit solution, 2nd round would be 30 min phone interview, 3rd round will be 1 hour technical interview, where they give you problem to solve in your language and explain solution and implement it with code, and some questions about QA experience, I gave right solution, but unfortunately they didn’t choose me.
