Perguntas de entrevista de vagas de LMTS, Software Engineering da empresa Salesforce

I applied online. 2 HR contacted me at the same time for 2 different openings. Finally they fought among each other and they agreed me to interview for one of the position. My online interview was setup surprisingly interviewer never showed up. I received a rejection mail after a month. I contacted the HR explaining the situation and they again setup my interview for another role. Round 1 was coding and I solved the question in 30 minutes and talked to interviewer for the rest of the interview. My feedback was "OK" and not strong. Round 2 was Low Level Design Round and the interviewer started asking me questions about how compilation works in Java and copy pasted a Java code from her working repository and asked me to explain the code. For someone who has been working in .NET and Python for last 4 years I was speechless for the whole round. For one of the best employers out there I never expected such incompetent HR and interview panel.
