HR contacted me immediately after I uploaded resume and scheduled a phone interview soon enough. The interviewer was nice and patient, even if I found my skill sets did not match the job requirements.

Domanda 1
Took 5 to 10 minutes to review my research projects.
How to deal with 1 million possible factors that may affect revenues, how large the data should be? And then two questions related to linear regression and logistic regression, respectively.
- Asked foundational questions about key definitions and terminology to assess baseline understanding of core concepts
- Completed a timed online coding assessment covering practical programming challenges and problem-solving ability
30 minute phone screen with HR, followed by an interview with the hiring manager. HR would not even provide a salary range for the role, which was very weird. The HR rep was not familiar with the role and seemed to be reading from the JD when I asked questions about it.
