1. Voting

Each voter can vote in zero or more referenda. Each referendum has one or more questions, and each question is a yes/no vote. Write the simplest normalized schema to describe this in generic SQL statements or as an entity-relationship diagram. Point out where the indexes would be if you want to quickly know the results of a given referendum question, but you never expect to query a single voter's voting record.

2. Availability on AWS

Your client plans to host their web application on AWS. When would you advise (a) deployment in a single availability zone, (b) deployment in multiple availability zones in a single region (c) deployment in multiple regions? What operational difficulty or complexity, if any, is added as you go from (a) to (b) to (c)?

Hi David,
My name is Jeff Morse. I'm a Recruiter at a super-charged start-up called Mixbook www.mixbook.com    I came across your profile on workingwithrails and have a full-time Sr. Ruby on Rails opening working onsite in our Palo Alto, California office that is a great match for your background/experience.  Would you be ready to make the move to Silicon Valley, the most innovative place for web start ups which offers superior growth opportunities for talented ruby developers like yourself? Mixbook will pay for all relocation costs. 
Would you be open to taking a phone/Sykpe call from our CTO, Aryk Grosz (see attached LinkedIn profile) to discuss the position further? If interested, email me your Skype ID and I’ll coordinate the call with Aryk.



Cheers,

Jeff Morse
Sr. Recruiter
