Tip
Tip

Tip 1 : Make you Data Structure and algorithms , Problem solving strong ( use to do some dsa problems on code studio and leetcode daily.
Tip 2 : Practiced Quality questions and mostly asked questions list available on codestudio( used company tags and topic tags) as quality matters more than quantity of questions .
Tip 3 : Give mock interviews, this really helped me as it gives you clearity and builds confidence.
Tip 4 : Read respective company’s interview experiences available on codestudio and other websites before going to actual interview, as this gives you idea about level of interviews and you can prepare beforehand.
Tip 5 : after solving dsa problem .Try to look in discussion section too as you can get more optimised or more efficient approach used by others to solve the problem.
Tip 6 : Prepare important concepts from Operating system,DBMS,System design too as that might also be asked.
Tip 7 : Do atleast 2 quality projects.
Not a Tip But : Lot of quality content available online, whenever felt like stuck with some concepts take help from senior or colleagues ( I use to watch coding ninja shorts by parikh jain whenever felt demotivated or stuck with concepts)
