Signed an NDA, but most questions were very open ended and required “practical solutions”, although some coding problems and puzzles/brainteasers obviously had right/wrong answers. My feeling is that they really try to make sure you’re a cultural fit to TS collaborative culture.
3 Q for the OA with one linear interpolation and one prediction of the temperature of the city based on 5 towns. The last one is the bonus and just increasing the number of towns.
calculate the sample size for a t test to be significant, given sample mean

For code interview: one array problem, one dynamic programming question, one question about some statistics calculations. For phone interview: How would deep neural net perform if the test data is outside the boundary of train data; calculation of correlations and some brainteasers
