COVID-19 Interview Experience:

Since I had a great resume (ex-Lyft, ex-Airbnb, ex-Segment), the recruiter scheduled a virtual onsite, skipping the technical phone interviews. I asked the recruiter for four weeks before the interview so I could prepare for it. Here's what I did:

Coding:

• I solved all the medium problems in the "Cracking the Coding Interview" book.
• I also solved 20 medium and 5 hard questions on LeetCode.
• I booked two chesky.ai interviews a week before the interview.

System Design:

Didn't really prepare much, since I have a ton of experience as a senior engineer.

The interview lasted for about 5-6 hours. It was surprisingly not too overwhelming. I definitely prefer this style over onsite interviews, to be honest. The only downside was the system design portion. I had a whiteboard facing the camera, so the positioning was rather odd.

For folks interviewing virtually (I guess everyone right now?), get a whiteboard and face it in front of the camera. Trust me. You'll appreciate this advice :)

Design "stories" (like Instagram and WhatsApp).

Stories disappear after friends view them and are only available for 24 hours after publishing.
