Teladoc Health Data Scientist interview questions

Long process, went through 4 interviews. First small SQL query to be sent in half an hour, then a 2h challenge, half SQL half use the tool you want to analyze some tables they sent. Then another interview with the data manager who asks you how would you explain stakeholders what is a p-value. Finally last stage a panel interview with 4 people where they never mention whatsoever anything about the data challenge, just ask you questions like 'how would you calculate the probability of a coin falling tails 3/3 tosses'. No assessment of actual skills, just questions out of the books on what the data analysts assume is skills on statistics. Very bad process and very disrespectful of the time you end up putting over a month of interviews and coding.

In my case, a first interview with RRHH about your academic & work background, then they sent you a simple SQL exercise. There is another test then but with python.
