The first round is a Karat interview. After the interview, the results will be sent to PayPal eval. It involved a simple transaction problem with around 3 levels. The data structure includes fields like number, sender id, receiver id, and date. The task was to implement a function that takes sender, receiver, and date as input and returns a filtered dataset. The solution involved setting an id = {sender}-{receiver}, then sorting by date and summing up the numbers. The interviewer will transform the data received by the function into q1-q3, requiring classification during filtering.
The second round is an onsite interview lasting 4 hours, consisting of one round of LC, one round of component, one round of SD, and one round of HM.
