It was a really long and annoying interview process. I had five technical interviews over video. Then, they had me come into the office weeks later, but the person I was supposed to meet wasn't even there. I ended up interviewing with two other people. The hiring manager reached out over the next few weeks with good news, but said they were still talking to other people. I eventually got an automated rejection email. The whole thing took about two months. I emailed the hiring manager to thank him and asked him to keep me in mind, which he said he would. Then, they posted the same job again a week later.

Technical Coding
After I applied to SolarCity on Indeed, I got a call in about 2 weeks for a video interview that was scheduled for September 15th, 2015. Right after that, the recruiter set up a call with a Senior Software Engineer at SolarCity. The interviewer was really chill and easy to talk to.
Confirmed questions3 questions
- Can you tell me about the projects you've done?
- How would you handle a situation where two different applications require the same database?
- Imagine you have 10 stacks of bricks, each with 10 bricks. Nine stacks have real bricks weighing 10 pounds each, but one stack has fake bricks weighing 1 pound each. If you take a collection of bricks (e.g., 2 from stack 1, 3 from stack 4, etc.) and weigh this collection just once, how can you determine which stack has the fake bricks?

Technical Behavioral
I was brought to a conference room and met with 4 people. They asked me some technical and process-related questions. They also reviewed my resume and asked about specific projects I've worked on. There was some waiting around because I later learned that 12 other people were interviewing at the same time.

- Could you explain what boxing is?
