I was approached by a Talent Acquisition via LinkedIn. He asked me for my latest resume and processed my application. The 1st step was a quick discussion call with him via GMeet (All interviews were held via GMeet). He was really helpful even when suddenly I couldn't attend the discussion so he rearranged the schedule. What he asked, in general, was about my previous experiences, what I did there, what my core skills are, and any general questions. He said that the whole steps would HR interview, HackerRank test, 1st user interview with the prospective direct manager, 2nd user interview with the direct manager of the candidate's prospective direct manager, reference screening, and offer. I think the time it took between each step was relatively short. On the same day I finished the HR interview, he sent me a link to the HackerRank test. The test consisted of Python and SQL coding tests, and multiple-choice questions on the topic of DS/ML/DL. In parallel with the technical test, he said that his colleague would contact me to tell me about the 1st user interview. His colleague also answered me about anything I should prepare for the interview, such as questions to be anticipated, During the 1st interview, the interviewer introduced himself clearly. The interview was in English as he's not from Indonesia. The interview nuance was relaxed enough. He asked me about my previous experiences in more detail and technical. He also asked me about some theories (and the formulas if applicable) of data science and machine learning, e.g. what you would do when given noisy data (what preprocessing steps you would carry out), variance, covariance, correlation, recall, precision, F1-score, examples of when you need precision over recall and vice versa, what do you know about A/B test (what steps you should do), and some study cases. He also added my answers when he thought they were still lacking. A few days after, I had the 2nd user interview. This interview was also in English as the interviewer is not also from Indonesia. The interviewer was also nice to me as the interviewee. In the 2nd interview, the interviewer also asked about my previous experiences. All the questions he asked me were mainly at a higher level than in the previous interview. He also asked me if I had an experience where I wrote a custom loss function (could be from a paper) of a deep learning model. Just a few days after, I was informed that I passed all user interviews and the HR team asked for my personal documents for further processes.
