Tip 1 : Competitive programming plays a major role when you are appearing for coding rounds as a fresher. In the coding rounds, you won't get direct problems copied from Geeksforgeeks or Leetcode. You would be required to use your logical thinking to go ahead in the process. This is where competitive programming helps.

Tip 2 : Coding rounds are all about Coding + Timing. Most people fail to excel due to the pressure of a timer ticking on your head. So, instead of just solving problems, try to participate in timed contests. This will help you be used to the pressure of the timer.

Tip 3 : Many big companies like Microsoft, Amazon, and even Google expect you to be good at standard problems. So, once you are done with coding round by your logical skills and competitive programming, you must be well versed with some standard problems in order to excel.

Application resume tips for other job seekers

Tip 1 : Make it short, crisp, and simple. It is always good to have a 1 pager resume. 
Tip 2 : Resume must comprise of the following: Educational Qualifications, Technical skills, Projects, Work experience (if any), Achievements. Other than this, you may include some extra co-curricular achievements.
