Tip 1 : Prepare Data Structures topic by topic and also solve at least 10 interview questions from each topic. The have a list of excellent questions.
Tip 2 : For system design try to take few questions by yourself and think of what different scenarios can arise considering it as a distributed system. There are multiple topics like Consistent Hashing, Partition tolerance, Availability, Sharing etc which needs special attention. The interviewers will dig them deep and will try to see how much of it you actually understand.
Tip 3 : Also please do focus on LLD. Sometimes they can ask you to write sample code for problems. Try solving 4-5 problems.
Tip 4 : You should do and prepare properly 2 -3 projects and try deploying it. You will face a lot of new challenges which you do not face in normal day to day usage.
Tip 1 : You can go for 1 page resume, though it is not necessary. Mention about your projects, your actual contribution, languages that you have used in that project etc.
