EXPRESS ENTRY PROFILE UNDER 4 JOBS (B level) Multiple NOC CODE

[Himanshu Sharma1991]

Hi everyone,
I am a confusion here,in last 1 year I have done 4 different jobs (all are same B level ) but different noc codes.
Next month I will complete my 12 months of experience (started job may 1 2017 - sept 2018) I Have some gaps in between as well (because of some emergency issue) ,can I apply express entry under CEC ?
What are the documents requirement for such cases ?

Thanks in advance
