Laravel Queues for multi user environment

I am using Laravel 5.0, and I have a task that takes around 2 minutes to process, and this task particularly is generating a report...

Now, it is obvious that I can't make the user wait for 2 minutes on the same page where I took user's input, instead I should process this task in the background and notify the user later about task completion...

So, to achieve this, Laravel provides Queues that runs the tasks in background (If I didn't understand wrong), Now for multi-user environment, i.e. if more than one user demands report generation (say there are 4 users), so being the feature named Queues, does it mean that tasks will be performed one after the other (i.e. when 4 users demand for report generation one after other, then 4th user's report will only be generated when report of 3rd user is generated) ??

If Queues completes their tasks one after other, then is there anyway with which tasks are instantly processed in background, on request of user, and user can get notified later when its task is completed??
