I sent my resume in June 4th and did not receive an initial response. My Gmail client may have deleted their email to me because on June 20th, I received a follow up email expressing their interest, but had not received the "Homework" assignment. I requested the information again, politely telling the recruiter what may have happened, and was promptly given another email with the attached assignment on the 23rd. I filled it out and sent it in June 24th.
I received a "Great News!" response that same day, and gave them my Skype availability which they promptly set up an interview on the 26th, which went very well. I had read some reviews where people were asked for the position right at the initial interview, but I received my offer today the 27th via Skype call on my cell phone.
