I applied online. The process took 2 weeks. I interviewed at Freelancer (Sydney) in Jul 2021
Interview
HR reached out after I applied online to give a HackerRank test involving some fairly easy Python and SQL questions.
After completing the test, HR reached out again to set up a 30 minute phone interview with the hiring manager. This included some very basic technical questions in 3 categories (Python, SQL, math/stats) and an opportunity to ask any questions I had about the role.
Finally, I was given an hour to finish a test my fundamentals in maths/stats, coding (Python), SQL, and machine learning. Two interviewers then spent about half an hour going through my answers and approach.
The interviewers are very knowledgeable and it is an enjoyable interview if you like learning.
Interview questions [1]
Question 1
Technical questions testing your knowledge of the fundamentals in four main categories: maths/stats, coding (Python), SQL, machine learning.
- Contacted by HR to discuss motivation/interest/background
- Short phone interview to discuss motivation and cover Python/SQL concepts
- Interview covering motivation and background + 45 minute written test covering a broad range of concepts (Programming/SQL/Unix/ML Concepts/Probability/Experimental Design). Written test was discussed with interviewers to gauge answers.
- Final interview focused on statistical concepts to gauge thinking process and technical background. (1-1.5 hours)
Interview was unpleasant and strange at times, a broad range of concepts were expected so would recommend preparing, low remuneration, HR/interviewers were flexible with scheduling, did not think I would be a good team fit.
Interview questions [1]
Question 1
Programming/SQL/Statistics/ML/Experimental Design/AB Testing
Each stage had more difficult questions.
Application online, then an online assessment concerned with SQL and Python, writing simple SQL statements and functions in Python to solve the tasks, and then go to a technical telephone interview with the head of the data science team.
