Interview
The interviewer I had a couple weeks ago was an incredibly inconsiderate and unfair person. He was awful. When I mentioned python to him, he said he never did python and didn’t know it even though it was one of the only two languages listed on the job posting. The whole time it was extremely unconventional. Ye would just copy and paste questions from leetcode and if you didn’t do it how they did on the website, he didn’t like your answer. You could hear him watching videos on his end throughout the technical interview which was not only incredibly unprofessional but inconsiderate as well. I hope they can find better interviewers that are not only more fair, but considerate of others as well.
