The candidate applied for a Sr SDET role in Mastercard Pune via the career portal.

First Round: Hiring Manager : Technical Screening (30 mins)
This round included basic Java questions such as reversing a string and writing XPath. The interviewer was friendly and explained details of the product and the role's responsibilities. Follow-up Java questions included: "If an object cannot be created from an abstract class, then why do we have a constructor in an abstract class?", "Can we have a final constructor in Java?", and "Can we have a static constructor in Java?". Coding questions included the Fizz Buzz problem. Another coding problem involved merging two arrays into a third using only one for loop (e.g., arr1: {1,2,3,4,5}, arr2: {6,7,8,9,10} -> arr3: {1,2,3,4,5,6,7,8,9,10}). A final coding question was to swap immediate elements in an array (e.g., Input: {18,45,7,10,5} Output: {45,18,10,7,5}).
