Interview Question

Data Scientist Interview(Student Candidate)

Three coding problems, can choose whatever language I am

  comfortable with for each one. The first one is similar to sorting & searching question. I did it in R, but last four cases didn't pass because of the time complexity. The second and three are more like statistical modeling of predicting humidity (continuous response variable between 0 and 1) and predicting temperature (continuous non-negative response variable). My initial idea was to use autoregressive model but I had never learned it before. Screw on problem 2 but wrote something regarding what I thought as comment. The test duration was 120 minutes, and I submitted everything just before it ended.
