Two interviewers took my interview. They asked questions about Data Structures, SQL and Basic Programming. In Data Structures, they asked about Tree Traversal and Circular Linked list. In SQL, gave some questions to write SQL query. In Programming, they made me write programs for implementing circular linked list and factorial.

Written quite technical and then followed by 3 rounds of technical interview. Interview and written based on basic electronics and aptitude. Lastly hr round. It took around a week for all.
