Phone screen with recruiter than 4+ hour long interviews with different teams and different people. 30 minutes of whiteboarding and 30 minutes of phone conversations. I was offered the position but then right before I signed the agreement the recruiter told me the gave the position to an internal hire? It was never discussed and extremely unprofessional. I still am confused by why they decided to stick to a poor experience instead of making it right.

3-4 phone screens and on site. Questions are from Leetcode Medium-Hard. Quite honestly given the interview difficulty for an SDET Intern position your time and skills are better well spent interviewing for an SDE Intern position at another company
