    Video answer for 'Design a URL shortener.'
    +19

    "I studied Exponent's TinyURL system design video. My interviewer was asking many detailed questions on API design, schema, as well as data required to store. I found system design questions are bit high level instead of depth. I think should have detail design of API, schema and some additional flavors."

  • "During my internship at Inceptra Analytics, our team was working on improving the monthly reporting process for the operations department. I proposed switching from manual Excel reports to a Power BI dashboard to automate and visualize key metrics.
