I was referred by an employee. The interview process involves two technical interviews followed by an HR interview. I did not pass the first technical interview.

The interview took place on Teams and lasted almost two hours, with a short break in the middle.

There were two interviewers, and they were nice.

The interview began with me discussing myself. Then, they asked questions regarding my CV and my limited experience. This was followed by theoretical questions related to the role, most of which pertained to networks and topics from my Software Engineering degree. Finally, there were two simple coding questions.

I was not given a choice of programming language; one question was in Python, and the other was in Java.

The role was for the DOCA team.

First Question:

Python question: Find all unique elements listLang = [CPP, PYTHON, JAVA, JAVA, CPP]

Second Question:

java public int foo(List nums) { int x = -1; int y = -1; for (Integer num : nums) { if (x < num) { y = x; x = num; } } return y; }

What is the code supposed to do?

What is the problem? How can you fix it? (They said they weren't supposed to ask this question, they were curious.)
