Tip 1 : Students with good practice of java concepts are preferred. So study and code in java.
Tip 2 : Add at least 1 good project in your resume.
Tip 3 : They look for team players. So be confident with your answers and add achievements other than academics in your resume.
Tip 1 : Do not use the term "proficient" in your resume. Because the interviewer asks questions related to that area and if you are unable to answer that then it reflects unpreparedness. Instead, use the word "Intermediate" to depict your level of understanding of a particular skill.
Tip 2 : Add at least one good project in your resume and have good in-depth knowledge of the same. It increases your chances of selection

Interview Preparation Tips
Professional and academic backgroundI completed Computer Science Engineering from Delhi Technological University. Eligibility criteria7 CGPADeutsche Bank interview preparation:Topics to prepare for the interview - C++, Data Structures, Dynamic Programming, Algorithms, Operating Systems, Object Oriented Programming, Database Management System, PythonTime required to prepare for the interview - 4 monthsInterview preparation tips for other job seekers
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.

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.
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.
