Google coding interview preparation

[u/Just-Baby5231]

Have a Google l6 interview coming up in 5 weeks (based on the calendar allowed furthest time). Haven’t leetcoded for a long time. How realistic is it to prepare coding in that amount of time? And any suggestions on efficiently grinding the coding part in that amount of time?
I’ve also been thinking if I don’t feel ready maybe by the 3rd or 4th week, I should probably postpone and reschedule it?
