I applied online. I interviewed at EPAM Systems (Belgrade, Central Serbia)
Interview
Very detailed interview process. I was asked theoretical question in all areas of programming, including but not limited to programming basics, DSA, design patterns, testing, API design. There were two smaller, "practical questions" that were fairly simple and just served to verify
• circular linked list
• Binary search
• Custom iterator
• Singleton design pattern
• Fibonacci using recursion
• Pandas groupby
• Is and ==
• Descriptors
• New and call
• Memory management in python
• convert a string to uppercase without using inbuilt functions
Interview questions [1]
Question 1
tell me about production issue you faced in project
First interview with a guy who frankly didn't want to be talking to me and was not interested in me or answering questions. Seemed like he hated his job.
Next round. 2 hours of endless grilling on every technical question under the sun. Video interview where they did not turn on their camera and did not answer any questions that you had about the company. They said they'd answer questions, but when you asked, they said that's for a later interview, not this one. After 2 hours of grilling about what does this technical thing do and that syntax do compared to some other highly specific language syntax on python, sql, docker, kubernetes, aws, they then gave an easy sql question and a medium leetcode question where they expected you to be able to answer with working code without resources while they watched you code. The solution required some specfic formatting...but unless you spend your time remembering how to format outputs...good luck. Frankly, these guys are just out to make interviewees sufffer. Really...quite an unnecessarily painful experience. If the goal was to weed people out, they succeeded...but why torture their interviewees so much and for so long?

Question 1
what are the 5 class methods in python. Tell me what this command does and that command does in docker, kubernetes, and github actions.
They wanted python code on the spot where you can process a list of objects and tuples, put them into a data structure like a dictionary, do some data structure manipulations, and be able to output the the results as a tuple of objects.
I applied through a recruiter. The process took 2 weeks. I interviewed at EPAM Systems
Interview
There were three process:
1) Call with HR
2) Technic call
3) Call with manager
Everything was fast and smoothly
The technical interview doesn't have any pattern, but they ask mostly about language basis and most common principles like ACID and SOLID
