We interview at various schools on a regular basis and this is the first instance I have heard of that general process not working well - I will discuss with our HR but it sounds like there was some kind of miscommunication or confusion. From what you wrote it sounds like our team was not expecting your arrival and had to muster resources unexpectedly to complete the technical round. I apologize if there was any confusion, normally as I mentioned the process runs very smoothly and we have had many fresh developers join our team through this same process. As far as email, I'm not sure who you emailed or to where, perhaps you could go to our Contact page and submit a Business & Others contact form with more details so I can go explore?
