Implementation of a load balancer.

The person was arrogant and very stressed, which made me very uncomfortable from the start. To some extent, he felt obligated to give me the interview.

1. I performed the TDD, and it was correct for him, but he didn't let me finish optimizing the code even though there was still time and we started 5 minutes late.
2. He accused me of having difficulty initializing a Set, which is not true. I just forgot, but I was able to do it in 5 seconds maximum.
3. I answered incorrectly a question about why I used a Set and not a List.
4. He criticized me for not using Java features because I didn't use contains or indexOf. Although I know these methods, I also know that they involve two for loops instead of one. I preferred my implementation.
5. An instantiation judged "weird" by him, because I did it in the method instead of the constructor. I explained to him that we saved a memory slot as it was not needed at the beginning, thus showing my knowledge of stack usage.

Regarding the TDD, I wanted to be a perfectionist and went further by testing each instance (the constraint was 10 instances max). I forgot that my load balancer persists, so it already had an instance from my first test. The comparison therefore failed. His remark was that the 11th instance would not work, not the 10th. Sir, from 0 to 9 there are 10 elements. I compared the first 10 with 10 different elements, which is why it didn't work. Neither you nor I could see this, only I noticed it when I left.

In short, only subjective remarks from a person who doesn't have the level to evaluate your skills.
