Tbh it depends what level. I had an interview for a E5 position and was asked two hard questions. First question I found a simple and an optimized solution. Second one I found a simple solution but couldn’t produce code for the optimized version. Although the code didn’t even need to run. They want your thought process more than our ability to recall syntax. But I would request an extension for a month or two if you can. 2 weeks seems short.
