Airbnb Data Science interview questions

I submitted an application for a Data Analyst role through a referral. An HR person was in touch with me the same week, and I had a brief phone interview the next week. Having passed this stage, I skyped with a team leader. This interview was also relatively easy (mostly focusing on my experience and a few general role-related questions), including a role-related task we conducted live. However, the exercise caught me off guard, and this ended up being the last stage for me this time. Overall very friendly people and an interesting company.

I applied online in January and got contacted in March. The whole process took 3-4 weeks. I think the arrangement of the process is not very well organized, but it is understandable since they are moving so fast with their growth. The recruiter called me once at 7pm and replying email at night is quite common. The take home data challenge take me around 8 hours to finish for both the analysis and the presentation while they said it should be around 3-4 hours to finish. I think this is a sign why I failed the onsite data challenge. The onsite data challenge is only 4 hours...I don't even have time... I think this is also what they are testing you about. Since their pace is so fast, they need you to get things done or at least report some useful insights given a short time. Got rejected since I don't have much experience and didn't do the onsite data challenge very well.
