I submitted an online LinkedIn application and I quickly received an email from HR for a quick chat. I had an informal chat with HR since the practice manager was too busy to attend. The chat seemed a test to show if you were a culture fit, and, if successful, another formal interview would follow. Long working hours and higly confidential work seem to be the norm at the firm but unsure if this is reflected in the pay. HR did not seem to understand their own advert when asked questions back.
