Interview
Applied for a freelancer position online. You can find the process online: HR screening, Codility test, tech screening with tech staff, and 2 weeks sample project that will be presented to a technical employee from Toptal.
Interview questions [1]
Question 1
Codility:
find maximum value on a column (something that in pandas would be super easy). Though, I wasn't allowed to use pandas; some coding test that required a priority queue to be solved; question was about a cleaning robot going around a 2D matrix always turning right, and try to tell what will be the covered cells by the robot.
Tech screening: linear model, with categorical values, and missing values.
I applied online. The process took 6 days. I interviewed at Toptal in Oct 2021
Interview
First Screening is done with codility and there are 3 questions that need to be done within 70 mins.
Another screening was sharing screens while creating a model with a downloaded dataset. Very unrealistic goal for the problem. The task normally takes more than 2 hours but you're only given 1 hour while expected to do everything (exploration, preprocessing, plotting, modelling, evaluation)
(pretty rude rejection email too ...)

Interview
2 sur 4 entretiens : le premier pour faire connaissance en video conference, ensuite un test technique à réaliser rapidement dans les 72h (codage en python, utilisation de librairie data science, durée limité de 1h30, minimum point = 125/300) et enfin un deuxième entretien pour débriefer le test.
