I applied online. The process took 3 weeks. I interviewed at Indeed (Austin, TX) in Aug 2017
Interview
I applied online, and the hr replied to me next day. After a phone interview with hr, I was assigned an data challenge homework. After passing the homework, there was another technical phone interview, then followed up with onsite interview for four sessions.
I applied through college or university. I interviewed at Indeed
Interview
After meeting them through a career fair, they were fairly quick in offering me a preliminary interview. They gave me a data set and asked me to answer a few questions, very much like usual upper level statistics homework. They next gave me a Skype interview, where they asked me a coding questions, SQL question, and coding questions.
1. Take home assignment with 10 or so questions explaining the approach and why that approach kind of questions.
2. A VC with 2 + interviewers asking questions on data structures (merge of lists with multiple variations) + question on complexity of each variation + probability (Bayes theorem) + Experiment design
The interview seemed to me to have gone well as they keep increasing the complexity of the questions with increasing variations. It cost as I was struggling a bit with their 4th variation on data structure and probably a bit to recollect details during the experimentation design round. But it seems they have a very high standard and are looking for a full stack data scientist who is good as a software engineer, ML and statistics. Nonetheless, it was a good experience. They were quite fast with their interview results which was good as you dont have to suffer the anxious waiting periods.
Interview questions [1]
Question 1
1
merge 2 sorted lists + explain complexity
explain complexity of sorted()
i think there was one more variation here that I dont remember
merge 2 sorted lists with and return another with no repeated items + explain complexity
2
You want to buy a puppy. the owner chooses one of the litters at random and then chooses a random puppy in the litter.
Litter1 = [brown,brown,grey,grey] , Litter2 =[brown,brown,brown,grey,grey]
1. What is the probability of getting a brown puppy?
2. If you got a brown puppy, what is the probability it came from L1?
3

did any corp have an unusually large amount of deaths. explain approach in detail
4.

Explain pvalue
How would you test for normality
How would you compare and test non-normal distributions
Explain Mann Whitney u
