Yes, after you get the email for file number they will assess all your documents. If all are proper, your expression of interest will go in pool for assessment.
In my case, I got file number email on 19 April, documents were delivered on 10 April. But within an hour the email came that I have to re send the AINP form as spouse hadn't signed. So had to suffer two weeks delay due to negligence of agent, who didn't make my spouse sign the form. Even for signature from lawyer they took 10/11 Days and form reached Alberta on 2 May and I got email of confirmation on 3 May
