It took me around 15 minutes via skype. The process is so fast, I got interview invitation just 5 days after submitting application form. The manager was not happy and patient. She gave me fast question and required me answer at the time, no time for thinking.

If there is a short-term consultancy open and they need quick support, that's your best bet for getting hired. It's especially helpful if you're referred by someone internally, because short-term consultancies don't necessarily get posted on the organization's website or other hiring sites. This is also a way to bypass the typical JPO process and get a foot in the door if you're under 32.
