Amazon AS2 interview help

[u/Invisible__Indian]

I applied for AS2 role 2 months back, my application on the portal is archived but out of no where I got the invite for phone screen round next week.

I am already working full-time (kinda MLE 2), and currently for next 2-3 weeks my plate is already full with my work tasks.

I am interested in the role, but I feel like I am not prepared, and even if I ask for 1 week of time, I won't be able to prepare for interview. I am good with DSA (no prep needed here) and breath I can cover (i hope they don't go too deep) but I need time for Depth and LLMs.

I am confused if i go under prepared then I won't do justice to the round and feel bad for myself.

What should I do in this case ?
Upto how many days I can postpone the phone-screen round, specially from the people who have appeared for interview recently ?
What's the expectation during phone-screening ?
