Got this from a recruiter:

Hiring Mode: Contract

Must have skills:

· 10-12 years mobile experience in developing Android applications
· Solid understanding of Android SDK on frameworks such as: UIKit, CoreData, CoreFoundation, Network Programming, etc.
· Good Knowledge on REST Ful API and JSON Parsing
· Good knowledge on multi-threaded environment and grand central dispatch

· Ability to work independently
· Experience with Agile Driven Development
· Up to date with the latest mobile technology and development trends
· Passion for software development- embracing every challenge with a drive to solve it
· Engaging communication skills

My response:

I am terribly sorry but I am completely not interested in working for anyone who might think that this is a job description for an Android engineer.

1. Android was released in September 2008 so finding anyone with 10 years experience now would have to be a Google engineer.
2. UIKit, CoreData, CoreFoundation are all iOS frameworks
3. Grand Central Dispatch is an iOS mechanism for multithreading and is not in Android
4. There are JSON parsing frameworks, no one does that by hand anymore

Please delete me from your emailing list.

Wow. All these weekly rants work so well with my current project lol.
A 4-5 year old iOS project, written in Objective-C with some jQuery thrown in to keep things interesting. Its the kind of codebase where you look at some code and think "what the....how....you know what nevermind". Everything has CoreData mangled into it somewhere which causes all kinds of issues. got search results from a web API? better save those to CoreData. Why? Who knows...

CoreData can suck a dick.
