Applied online, waited for 2 months, no reply. Asked my friend to refer and got an on-campus interview for SDET, but hadn't heard back for more than 2 months. Submitted my resume at a career fair, waited for another month, and finally got the onsite.

1. How much percentage of energy can we receive from the sun? (Given the distance from Earth to the Sun and the radius of the Earth). Didn't get the answer, but the interviewer said it was okay since it was a weird one. Given an array, how to find the frequency of each character in the array without accessing it a second time. The interviewer said a hash table doesn't work, but an extra array does (actually, I thought both of them worked in the same way, but didn't indicate that to the interviewer). Print a tree (not a binary tree) level by level (got a little bit stuck on the level-by-level thing), and got the result in the very end. The interviewer didn't want me to code everything but to describe the logic.

2. ER graph represented the relationships and entities of a social network website like Facebook. Draw tables and optimize. OOD concepts and related code.

3. Given a bunch of ranges (e.g., 1-5, 2-8, 30-78, 40-60...), output (1-8, 30-78). Print a BT in zig-zag order.

4. Chatted a lot! Implement a stack with memory constraints. Writing test cases. I wrote some basic ones but obviously didn't satisfy the interviewer. Struggled a lot to extend in terms of memory.

5. With a test manager, no technical questions at all.

Most of the interviewers were very nice and provided helpful guidance on how to work things out. Absolutely positive experience.
