Np. If you have enough time, then start with doing one problem every couple of days from Leetcode. If you feel overwhelmed, then you can join a classroom course/bootcamp where you will get regimented preparation, like-minded people and a lot of help from experts. If you are not overwhelmed and enjoy the self-paced practice, then all you need, is some fake/mock interviews with seasoned interviewers, to make sure you are on track. Those you can do by applying to companies that you don't want to work for, or you can do those with us (http://InterviewKickstart.com http://InterviewKickstart.com).
