EPAM Systems interview questions

1 test, tech round online. Interviewer was very rude, did not even smile at all. He did not want to hire, he was just doing time pass. Only he can clear his interview as it was very specific to some project, if you did not worked with him, you can not clear. n asked questions like how to break Singleton pattern, what is setting in lambda to make it Ec2. Questions on Scaling, Kafka etc.

Se tardaron como 3 meses en concretar el proceso de contratacion. La verdad yo crei que ya no me iban a hablar. Parece ser que el cliente estaba indeciso en que perfiles era los que necesitaba. Afortunadamente al final las cosas se resolvieron a mi favor.
