    "I always ask to clarify if this is a brand new team. If so, then I focus on bringing in people with strong technical aptitudes(since I'm hiring for software engineering), but also team members that have experience mentoring and good communication is a must. I look for people who have leadership qualities. I emphasize that building a brand new team isn't something I can do on my own, so the initial hires of that team are very important to help me expand it."

    Video answer for 'What are common linear regression problems?'

    "I can try to summarize their discussion as I remembered. Linear regression is one of the method to predict target (Y) using features (X). Formula for linear regression is a linear function of features. The aim is to choose coefficients (Teta) of the prediction function in such a way that the difference between target and prediction is least in average. This difference between target and prediction is called loss function. The form of this loss function could be dependent from the particular real"
