I applied through a recruiter. I interviewed at Google
Interview
Got a reply from recruiter with the questionnaire after 2 days of applying online. After questionnaire, schedule a phone interview.
Interview questions [1]
Question 1
1.When to use mean and medium?
2. For sample size n, the margin of error is 3. How many more samples do we need to make the margin of error to 0.3?
3. X is draw from the normal distribution of mu with standard deviation of 1. Decides whether mu is not zero. So I do the hypothesis testing. How reliable the test is?
4. Coding Question -> write a function to generate N sample from normal distribution and plot the histogram.
It was all good, the interviewer was very nice. Technical questions were a bit challenging but overall it was good. The hiring manager was looking for some hands on experience
Back to back interview.
