I did some analysis...
So first, lets look carefully at the data.

With that in mind, lets analyze the username length of people applying.

As you can see, longer names are more popular. But what does that mean?
If you plot username legnth against total posts you'll find this:

Clearly the polynomial function can be best described as asymmetric and probably difficult to accurately estimate. The negative correlation suggests that those of you with shorter names are more lazy and post less, and thats probably why you picked a short name in the first place.
Now if we take this data and plot your entries against the number of posts you've made divided by your username length and square it you find this.

Suggesting that mNeo is totally statistically posting more than his fair share. Good on him!
Now if we plot the difference in times you submitted your application to the number of posts we find:

As you can see, there graph is really kind of nuts. I think it says a lot.
Finally based on this data we can estimate the hot admit zone

If one intends to climb into the hot admit zone. you have to traverse the lillifores steps and write proper essays. This can be seen in the below graph.

Excited yet? These guys are:

Now if you plot the MOON PHASE AGAINST INTERVIEW INVITES, YOU GET TIHS INSANELY STARTLIN GRAPH:

HOLY !@!! DO YOU SEE IT??
INTERVIEW INVITES CORRELATE WITH THE PHASE OF DA MOON
And just look at the regression !!

Amazing stuff.
Conclusion: The best predictor of an interview invite is the moon's phase on the day you submitted!
(Ok, now i need to go study)
