I applied online. The process took 1 week. I interviewed at Freelancer (Sydney) in Sept 2019
Interview
I applied online and got a call from the HR to give a technical test. The test can be given in any language. The questions were easy to tough and included puzzles and SQL queries. I got around 85% marks in the test and got the call for an in person interview. The interviewer was very arrogant and had a bit of accent. He asked me to tell about myself and when I finish he said 'Oh I didn't hear can you repeat it again'. He then started asking questions about Python and tried to dig me deep by saying that my answers are wrong, but anyway I was confident enough to stick to my point. Next was some questions from SQL query which he wrote a query and asked to give output. Last section was on maths and stats and asked lot questions from probability, equations of linear regression and few machine learning concepts. In each and every question he tried to confuse me to check my confidence. Interview went for more than an hour and was my worst interview experience ever.
Interview questions [1]
Question 1
Tuple and Lists in python. Joins in SQL. Normal distribution in maths. Random forest, decision tree in 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.

Question 1
Programming/SQL/Statistics/ML/Experimental Design/AB Testing
Each stage had more difficult questions.
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.
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.
