EPAM Systems interview questions

1. Recruiter phone screen interview. 2. Technical interview(1:30 hour). 3. Project team interview(1 hour). The technical interview asked some technical questions and coding challenges. What is a decorator in Python? create one. Gave code snippet of the multiple try-except blocks and asked for output of each line. Gave code snippet of the multiple inheritances and asked output. What is the difference between docker and virtual machine? Have you heard of WSGI and ASGI? What is a reverse proxy? The project team interview asked scenario-based questions. How you will test your code? What if another developer has to test your code how do you do that? How you will check your application running fine in production? How do you identify the error? What is the most important error you should look for? How do you test a scenario where the customer said API is not working in the production, but you test it locally and it's working fine. How do you test customer complaints in production?

The HR round and the online tests with algorithmic/logical tasks were straightforward, but I failed the manager interview as I couldn't really solve the coding question. The manager said I could try again about a month later.
