H1B dropbox status refused

Hi Folks my timeline.
Dropbox: 26th March
AR1: April 4th
AR2: April 12th
Refused: April 15th

Getting a bit worried now. This is not my 1st stamping.
Back in 2011 I had a refusal for F1 visa for a top tier uni and in subsequent appointment I got the F1 stamping. Thinking about refusal, at that time I was not speaking aloud and probably underprepared for visa interview.
Currently I work at FAANG FT SWE role, no consultancies.
Just reaching out to the community for some words of encouragement and guidance.

Update 1: Picked up passport on 17th from Delhi VAC. Have been requested in person interview between 9-11 Am in chennai. One puzzling document requested is LCA. Other documents are I129 and i797’s (historical too).

Update 2: Attended Interview in Chennai on 18th April. Outcome: Approved Documents asked by officer: Passport.

Although 221g slip mentioned LCA, I129s and i797, I went with these but none were required. Interview details: officer just asked for passport and scanned my fingers, then took passport and walked away then came a min later and said it’s approved.

Update 3: Got visa issued on April 22, picked up on 24th. On my way! Back to work now.
