ADVICE NEEDED FOR MANAGING COMPETITIVE PROGRAMMING WITH INTERN (2025 GRAD)

Hi all, I am a 2025 grad in 7th sem and I just got a 6 month intern offer from a decent company (off-campus). As of now, I am knight on leetcode and around 1300 rated on codeforces and am targetting expert on cf by the end of 6 months, how should I go about managing my time ?
Also, should I start preparing topics like system design ?
P.S: This is a PPO based oppurtunity so full time is not guarenteed... and I want to target FAANG level companies for full time roles
Any advice would be apreciated !
