It’s Amazon Software Engineering.
I think Amazon and Microsoft are LMIA exempt.

The companies themselves are not LMIA exempt. If something is LMIA exempt, then it would need to be the specific job / occupation. Note that without an approved LMIA, you will be at risk of losing the 50 job offer points if IRCC figures out that you have switched employers. However maybe you are above the draw cut off even without the 50 points.
 
Will there any CEC all draw I dont see much happening

Anything is possible. It could happen. You will want to have a score well above 500 to make sure you are selected if it happens.
 
Not really sure tbh. I didn’t apply they reached out to me on LinkedIn and after I said I don’t have PR yet they mentioned we can sponsor your visa if needed.
Now I’m delaying that as I got P1 so ecopr should come soon hopefully

Are you sure this is truly Amazon? Amazon contacting you out of the blue on LinkedIn and willing to support your PR application seems very unusual. Given the tech layoffs Amazon not desperate to secure software engineers. I could potentially see them perhaps supporting a longterm employee but given the current tech job market not sure why they would go through this hassle or expense or be contacting people out of the blue. I’m sure tech workers looking for work contact Amazon not the other way around unless you are some top grad that is being headhunted.
