I applied for a Data Scientist position and received an online assessment relatively quickly. However, after completing the OA, I didn’t receive any further updates from the company. There was no follow-up interview or communication regarding the next steps.

The interview process consisted of several stages. First, I had a phone screening with the recruiter. Then I had a 30-minute phone interview with the hiring manager. After that, I was given a dataset and a set of tasks where I needed to perform data preparation, exploratory analysis, and build a prediction model; I uploaded my completed work for review.
Next, I participated in a 4-hour panel interview with a team of 4–5 people, during which I walked them through my entire workflow and answered technical follow-up questions. I believe there was also one final step after that, completing the overall process.

One of the questions I was asked in my data science technical interview was to flatten a nested dictionary. The original dictionary contained a mix of dictionaries and lists as values, and those lists and dictionaries were also nested inside each other. My task was to fully flatten this structure into a single list.
