This gets discussed almost every day. You'll find lots of opinions[]

I personally think the mistake most people make is to go heads down and assume they know how to prepare.

I spent X*10^3 on preparation, between 3 or 4 different services, and added 10^6 to my TC in one job hop.

So I see it as an opportunity rather than an obstacle.
