First talked to the hr about some basic information. Then did two online assessment. The first one is use python (no pandas is allowed) to parse some csv files, two questions in an hour, very easy. But I have no idea why they ask these useless questions. The second one is to build a time series model to predict stock price and submit within 14 days. The problem badly framed and very ambiguous, it doesn't say what to predict and how many days to predict. I built a model using RNN and submitted but never heard back
