UBS visited our campus for a recruitment drive, providing an exciting opportunity for students to showcase their skills and secure positions in their esteemed organization.
Aptitude Test:
It consists of 15 mcqs related to quantitative and logical reasoning, and another 15 mcqs on CS core subjects like DSA, SQL, OS, JAVA, etc.
It consists of one coding question (Not the same for all). The coding question difficulty level was leetcode medium, related to the array, sorting, and greedy. Overall aptitude difficulty was easy-medium level.
Technical Round I :
Started with a formal introduction. Then 2 DSA questions, first on a linked list, and another on queue. 1st question link (you are not given the number of nodes. and the interviewer wanted a pointer solution in one pass)
Then they shifted to SQL. asked my query to get the highest salary of an employee department-wise, also without using aggregate function and more questions based on the same schema. Then from OS, they asked about multithreading, have you written any code on multithreading and how? Data structures used in OS, etc. What happens when you run a program (in detail)?
From the Project, they asked for concepts related to NodeJS, API calls, restful API, and different methods, gave one scenario, and asked me to design an API for that. OOPS, gave me code and asked me to predict the output (which constructors will get called). concept of virtualization, etc. Basic questions about C++.
I mentioned Cloud Computing in my resume. so they asked me why there was a need for cloud. basic services. and asked me by which means I can ensure the security of my data while using the cloud. Some non-technical questions, scenarios related to work-life challenges, etc. Overall it was a good experience, they were more interested to know my approach and my knowledge about a particular subject rather than the exact answer.
Technical Round II :
It lasted for 20 minutes. Mostly based on what projects you have done, and what features can be added extra, i.e. deeper discussion on my projects. simple array and hashmap question. asked me what is my favorite subject. a real-life example where the stack is used (not related to any computer system, he wanted examples from day-to-day life). Why normalization is needed? Advantages and disadvantages of normalization. C++ VS Java.
HR round :
How was your day. Why you want to join UBS. Family background. What you learned in 21 years of your life? cross questions on my answer. Role of data in this world. How is data different from information. Define in one line, how data is important for UBS. About my hobbies. Are you ready to relocate to pune, and all general questions.
My overall experience was great. Just let interviewer know what you're thinking, what's your approach. Be confident. And be carefull about what things you mentioned in your resume.
