Bluevine Python Developer interview questions

I was summoned for a first interview in the company offices with a team leader. The place is nice and cozy. I passed a test with 4 simple questions in Python - like - what is the difference between get and post(http), while understanding the maximum height in a binary search tree (possible in recursion) and more .. They then passed the test with the interviewer and he asks for explanations of each answer you wrote. Then I was asked to implement the Range function in Python. Then call for a second interview, in case you passed the first interview.
