I went through a comprehensive three-round interview process that was ultimately undermined by poor communication. Despite successfully progressing through multiple interview stages, the lack of responsiveness from HR became a significant drawback. My multiple follow-up attempts went unanswered, and after waiting over a month without any updates, my candidate experience was negatively impacted, suggesting a need for more transparent and timely recruitment communication.

Walked through datasets in R for the first interview, describing what steps I would take to make sense of the data. Two back to back interview in the second round with brain teasers.
