I have an onsite coming up in 2 weeks for SDE-1 position. I have experience of around 3+ years. I am juggling between tasks like ( OOD, System Design & DS Algorithms) and while studying one i tend to think about other two. Also haven’t started studying for LP yet.

What should be my strategy to make sure i am able to do really good during interview and be able to focus on all areas simultaneously ? (how did you devote time ? )

I work full time and possibility of taking time off is negligible.
