This was the phone screen. A couple of people were interviewing, representing two teams. The phone line wasn't very clear.

The interviewers didn't seem friendly and didn't make their questions understandable. However, I did request for them to repeat questions many times.

The technical part was solvable and wasn't hard, and I was given hints along the way. However, the interviewers could have been more polite and communicated the questions better, and paid more attention when I was talking about myself.

For example, I asked, "Does this function accept a parameter?" The interviewer didn't follow my question at first and made me assume. The second person had to jump in to resolve my doubt.

A better phone line and slightly more polite interviewers, and the result would have been very different. I had the preparation, but the lack of communication threw me off guard.

Given a JS object, obj = {a: 1, getA: function() { return this.a } }.

var get = obj.getA; console.log(get());

What will it print?

How can you prevent it from printing null?
