I am glad to share with you I just came back last night from my consular interview at the US embassy in Guatemala. My interview as Nov 30th 2021, I left USA 10 days before to get all the required medical stuff done, total time I was there was about 3.5hrs. the actual interview itself was just about 5 minutes, at a window. They asked me a few questions:
1st time I entered
2nd time I entered
How old was I both times
How long was in US the first time
How long was in US the second time
Why overstayed first time
What questions did the immigration officer asked me the 2nd time I entered
Where did I enter those 2 times
Did I use same visa to enter
Did I enter any other way at any other time
How old I was when I got DACA
What did I do before DACA, did I work?
Did my company petition me?
What do I do at my job?
Did I have an approved 601a?

The lady was very serious, dry and to the point. At the end she said, they had to check with US department of labor to confirm my employment with the company who file the petition (I-140 petition for alien worker). My company file this in 2018 and was approved in 2019. She took my passport and said if confirmed, they I would be reached by the designated courier service (cargo expreso in Guatemala).
I asked if I needed a confirmation or anything else, she said no. I did not receive any papers (green, blue, red, nothing) like other people have.
That the nigh I check the visa status with my case number it said in was under "Administrative Processing"
Next day it was updated to "Issued" (so happy).
In the next day it said it was delivered to courier, where I went to pick it up in person(the passport with my EB2 visa on it), and a large yellow envelope (my case was older and paper filed).

I had to do all the covid forms (attestation and covid tracing forms), and covid test 24 prior to my Monday flight back to US.
When I arrived in Atlanta the 1st officer asked for my passport and:
where I came from?
how long I planned to stay? when I answered that I live here, he asked how long and i had this was my first time entering with an immigrant visa and that I had a package with me (the yellow envelope), he grabbed that, threw in a clear bag with my passport, and called "Alpha" to get an officer to walk me to another window, next to this area. She said, sit down and we will call you by name, there were like 7 other people waiting for the same reason.
They called me by name in like 5-7 minutes. He asked, same 2 questions as above and also
where would I stay?
with whom?
was it a house or apartment?
name and phone number of the person living in the same house as me?

the he explained I would get the PR card in the mail in a couple of months, that I must not be out of US for longer the x amount of time to maintain it, and 1-2 things more he said, but I honestly was too excited to remember, but it was like regular protocol information. He asked also what did i have in my checked in luggage, if was traveling with more than 10K (no) or meats, cheese... and that was it.

I am back in USA, after 2o years living here, and finally seeing this dream come true. I truly hope for all of your cases to be successful. I know we all have to go through so many different hoops and struggles as our cases are so particular. Thank you all, @Demise, who have helped me with all the questions I have posted here.
