I submitted my resume via the web and received an HR phone call the next morning to schedule a technical interview a week later. I spent a lot of time preparing for the interview; all questions were from Glassdoor, except for one (see below). Based on other reviews, it seemed the ask-and-answer interview would last more or less 40-50 minutes, but mine only went 30 minutes.

Most questions were very easy and entry-level. However, you would probably get lost if you hadn't seen these questions beforehand, as the interviewer's accent was thick. For example, 'difference' sounded like 'defence'.

I was told to wait for further notification, but only 15 minutes later, my online status became 'not ideal match'.

What is the summation of 1 + 1/2 + 1/3 + 1/4 + ...?

Give the answer in no time. Are you kidding me?
