Entrevista
Initially there was an online test consisting of six questions regarding basic probability (mostly applications of conditioning). Then I had about a 30 minute interview with a recruiter who detailed the position. Afterwards I had a 30 minute interview with a junior memory of the data analytics team. He asked one probability question and one general question that was more in the realm of product management.

You're playing a game with a friend where some third party flips a fair coin. You can choose a sequence of either Heads, Heads, Tails or Heads, Tails, Heads. Your friend gets the remaining sequence. Whoever's sequence occurs first wins. Which do you pick?
I emailed an HR contact I was given and was then directed to take an online quiz. It was short, about 5 questions. The first few were pretty simple probability questions and the last one was more open ended/problem solving oriented. After that I was contacted to set up a phone screen which consisted of one probability question and one analytical question. I was then moved on to the next round, which was an onsite interview. The onsite interview was about 2 hours long and I met with 6 people. All of the interviews consisted of both behavior questions about how I would respond to a problem they are usually confronted with on a daily basis and probability questions.

I applied online and after several weeks a recruiter followed up with a link to do an online test.
I did the test but after some days I received email of not being selected which was a bit strange because I thought I had done the test well.
The questions in test were:-
I went out dinner last night and discovered that I charged 50.40$ in total for my meal. Tax is 5% and I always tip 20% of the meal +tax. If 60% of the cost of my meal was my entrée, how much did I spend on Entrée?
22.9$
