Perguntas de entrevista de vagas de Software Engineer da empresa Level Data

Applied via LinkedIn and I got an email for 30 minute phone interview. There were 2 interviewers and they asked me questions related to Talend and open-source contribution. They asked me few questions related to my past projects and it all went fine. Never heard back from them. I even sent them an email for follow-up. Its really rude when someone puts in efforts and they can't even reply even if its a reject
