It's been about a decade since I last had to look for a job. And, my oh my has it changed.
At the time Dice and Monster were the (relatively) new hotness and when you applied there, you generally got a response pretty quickly. Nowadays, Monster is a brutal train wreck of excess. I haven't looked at Dice lately and LinkedIn and Indeed.com have sprung up out of nowhere.
There are a massive number of jobs out there. For example, on Indeed if you search for "Los Angeles", you get over 60,000 listings. That's a lot of jobs. Unfortunately, I've found that applying for them is the equivalent of printing out your resume and putting it in the shredder. Actually, that would be more fun.
