Capital One Software Engineer interview questions

Initially there was phone screen technical round. They pose questions on basic javascript interview questions. Some questions I can remember are of : Difference between let & var keyword. Difference between == & === operator. What are Arrow functions.

Went through 3 rounds of interviews, last one was with 4 different people and lasted a total of 4 1/2 hours. Long interview process, and can be challenging; however, the interviewers were supportive and patient.
