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.

One phone interview and three video interviews. The phone interview was behavioral with an additional brain teaser. The three video interviews started with questions about resume/experience. They ended with problem set questions using quantitative and qualitative skills.
