Search insights on jobs

I tested the newly launched Google service called "Insights for Search" which is an improved version of Google's Trends.

I tested with a few search term and I tried the term "jobs".

Look at the pattern I got from this term:

I made a guess interpreting this graph:

People stop searching for jobs during Christmas holidays (this is easy to catch). Then they feel they need to catchup in january. They don't find any changes from the past year and they wait a little bit. Then they start again in springtime and they reach the top in summer (many might look for a summer job). After the summer the interest in finding jobs decreases again to its minimun again at Christmas.

Please post a comment if you have alternative interpretations of this pattern.
