Interview Preparation Tips

Professional and academic backgroundI completed Software Engineering from Delhi Technological University. Eligibility criteriaNo criteria.Goldman Sachs interview preparation:Topics to prepare for the interview - Data Structures, Database Management System, Object-Oriented Programming System Algorithms, Dynamic Programming, Graph, Puzzles, Operating System, Multi-Threading, projects.Time required to prepare for the interview - 10 monthsInterview preparation tips for other job seekers

Tip 1 : Focus on Data Structures and Algorithms. Practising questions based on them every day is the key to succeeding. You can enroll into a Data Structures and Algorithms course by Coding Ninjas. This course helped me build a strong foundation in these topics. I also recommend platforms like LeetCode and InterviewBit for further practice.
Tip 2 : During your interview THINK OUT LOUD!!! It is very important that you voice your approach towards the problem otherwise interviewer will have no clue what you are thinking. 
Tip 3 : Do give mock interviews to some college senior or mentor. They help you understand how to express your thought process better (Think out loud) and also reduce the interview stress and anxiety.

Application resume tips for other job seekers

Tip 1 : In order to make a strong resume you must include at least 2-3 Projects and an intern/work experience. Mention all your skills which you are confident of in your resume. 
Tip 2 : Try to make it of one page only. You can use overleaf to make your resume.
