Programming interviews – observations, tips

For the past 2+ years, I’ve interviewed more than 150 people for different Java positions, from junior to senior+ levels. During these technical discussions, I’ve observed a number of strange patterns repeating over and over again. Some of these are really counter-intuitive, maybe I’ll be talking about these in a different post.

All these interviews were really, really different, but one thing is…

You have eight balls all of the same size.

7 of them weigh the same, and one of them weighs slightly more.

Make it so that if you were to append the following code to a script:

var val = foo()()()()() + 3; if (val === 8) { console.log('the value is 8!'); } console.log(foo()()()()()()()()()() + " == 10");

the output would be:

the value is 8! 10 == 10
