I was initially contacted by an HR representative who asked me to rate my proficiency on a scale of 1 to 10 in various skills, including SQL, Python, Linux, Bash scripting, APIs, Spark, Scala, Kafka, Hadoop, Data Mart, BI, and Data Warehouse DB concepts. This self-assessment served as an initial evaluation of my expertise in these areas. Following this, I underwent a one-hour technical interview where I delved deeper into these skills, discussing and demonstrating my knowledge and problem-solving abilities.
