I applied for a DS role in Singapore. I passed the initial Python HackerRank test and then completed a take-home data science test. Unfortunately, two weeks after I submitted the data science test, HR informed me they decided to move forward with other candidates. I didn't get any feedback on the data science test. No voice or video calls were involved. I was pretty disappointed as I thought I did well on the assessment and deserved some feedback, maybe from the hiring manager.

The interview process started with an online test covering programming and database questions. After that, there was a take-home data project. Once I passed that, I had two more rounds, the 3rd and 4th, which were all online interviews. These interviews were with analysts and the hiring manager. There was also a caliper test before the 4th round. Everyone I interacted with, both interviewers and HR, was really friendly. The company was transparent about the process, but it did take a long time, so patience is definitely needed.

The process started with no human interaction. It included an 80-minute programming test on Hackerrank, followed by a data cleaning exercise that took several hours, despite being estimated at one hour. This process felt one-way rather than a typical two-way interview. If you value your time, this might not be the place for you.

- Two questions on Hackerrank.
