I am not able to tackle 3 months of notice period.

Check if your company provides buyout option, you can buyout 45 days of your 90 days notice period.

Start applying from the second month of notice. Use the first month to chill and upskill.

90 days np seems too much

Hearing a lot of this. Some companies even deny buy outs. Most of the companies that are hiring are looking for folks who are available immediately
