Interview Preparation Tips
Tip 1 : Be thorough with data structures and algorithms. Avoid just switching between different coding platforms according to people's suggestion instead pick one and stick to it(Leetcode worked for me!).
Tip 2 : Do not miss out on core subjects (for GS ,OOPs and Operating systems especially).
Tip 3 : Keep giving mock interviews (take at least 2 -3 prior to real one) ,it helps a lot to prevent last-minute interview anxieties and makes you feel prepared and confident.
Tip 1 : Choose the right format, it should reflect professionalism.Goldman Sachs blog suggests to arrange your resume with your educational information at the top,followed by your grade-point average,professional experience, projects and any special interests and activities or achievements.
Tip 2 : If you do not have any prior experience, solidify your projects section(3-4 is a good number).Articulate your project description in a precise and crisp format.
Tip 3 : Come up with three reasons why you should be picked for the job in accordance with job's description —these will be some of the top traits you’ll want to emphasize in your resume.
Tip 4 : Go through company's career blogs ,might give you relevant insights on what it expects then align your presentation in accordance with in.(Link to GS blog on resume tips:https://www.goldmansachs.com/careers/blog/posts/resume-tips-from-goldman-sachs.html )

Interview Preparation Tips
Tip 1 : Having proper knowledge over Data Structures and Algorithms is crucial. Have your concepts cleared and then select one coding platform( for example, leetcode, CodeZen, GeeksForGeeks) and try to practice at least 5 questions everyday topic-wise. I completed around 300+ questions on leetcode, 100+ questions on geeks for geeks and around 30-40 problems on InterviewBit.
Tip 2 : Focus on time and space complexity. Students usually ignore this fact. However, you should think about how you can optimize your code further. Hence, instead of trying to solve more problems, try to analyze it.
Tip 3 : It sometimes gets easy to demotivate but you need to keep practicing daily. Don't cut down your sleep and diet. Healthy lifestyle and personality development also plays a crucial part.
Tip 1 : Do not mention those skills, projects or achievements which you haven't achieved. The interviewer is intelligent enough to verify them.
Tip 2 : Do not keep your resume too long, and do not mention irrelevant details. One page resume for an intern is enough.
Tip 3 : Have projects related to the field which you are applying for, this shows you are already experienced in the field.

Interview Preparation Tips
Tip 1 : Practice DP based questions as much as you can. Also, be confident during the interview about your solution. For practice, you can prefer Coding Ninjas and Geeks For Geeks.
Tip 2 : They do not judge you upon the number of internships you have done or the number of projects you have made. A single ,good-quality project is sufficient, provided you have in-depth knowledge about it. What matters to them is how efficient learner you are, how good is your problem-solving skill and also how confident you are with your answers.
Tip 3 : Practice topic -wise questions, participate in lots of coding contests, watch lots of Youtube solutions even after you could solve a question, because you may find a different approach that is efficient than yours and watching video solutions is always a better option than just reading the solution , as it gives a clear and deeper understanding of the logic's . Also pray hard along with your preparation.
Tip 1 : Keep it short. Mention the academic and professional projects you've done. Add your educational details properly with percentage or CGPA obtained.
Tip 2 : Keep your resume short and clear. Mention your projects and internships with a brief description and year of completion. Mention coding languages are known to you, or other technical skills that you are good at. Do not mention anything that you are not good at. Highlight the topics that you are really good at.
Tip 3 : Be very honest and figure out only those things in your resume that you really know. Anything extra or unknown may have a negative impact upon your interview if asked by the interviewer.
