Interview questions [1]
Question 1
Tell me about a time when you have had to optimise code
Fun with challenging pseudocode problems.
Visited their office twice which seemed a bit unnecessary as they were not reimbursing for travel.
The interviewers were very understanding when working through problems.
The take home programming challenge in scala was difficult to juggle at the same time as university deadlines
The process took 2 weeks. I interviewed at Quantexa in Mar 2018
Interview
The whole process went very smoothly and quickly (2 weeks); All people that I interacted with were very friendly and kind. I felt very welcome!
1) Phone call with internal HR to assess cultural fit and discuss your professional experience.
2) On-site interview with small, yet very relevant coding challenge and some technical questions. You can also ask some questions with regards to the company.
3) Take-home assignment with 3 questions.
4) On-site interview with a discussion of the take-home assignment, presentation of a business case, small coding challenge and a discussion of another business case that is explained to you on the spot. You can also ask some questions with regards to the company.

- Small brain teaser question
I applied through a recruiter. The process took 4 weeks. I interviewed at Quantexa (London, England) in Mar 2018
Interview
The process took approximately 4 weeks and has 4 steps:
1- Call with the HR team to talk about your background, motivations and what you know about Quantexa.
2- Technical call interview with a Solutions Architect.
3- To do by your own: Assignment with 3 scala exercices.
4- Presentation of a project you'd made in the past and some questions regarding the Scala assignment.
The process in general requires you a bit of time to complete all the assignments. However, I found it really challenging and rewarding to complete them.
