Problem of the day
Tip 1 : For an intern position in any big company, the most important thing is practicing data structures. Solve as many questions as you can on platforms like Coding Ninjas. First start picking up questions topic-wise and once you gain a decent confidence in every topic, start hitting harder questions randomly on various platforms. (Practice a minimum of 300 questions).
Tip 2 : If you are stuck at solving any question, instead of looking up for a code solution try to read discussions and see various approaches people are applying. This will surely make you prepared for the way in which the interviews are designed. Always keep a clock ticking while solving a problem as spending too much time while practicing surely makes you slow in the Online Tests and Interviews.
Tip 3 : Again specifically for internship preparation, focus mainly on the subjects that have been taught to you till now. As in many colleges Database Management, Operating Systems and Computer Networks are not taught till the 4th semester so you could easily focus on subjects in your curriculum. OOPS concepts are very important!
Tip 1 : In On-Campus internship drives it is generally not required to have a very charming resume with a load of projects as the companies understand the candidate as a 4th semester student.
Tip 2 : But still if there is even a single decent project genuinely build by the student then it is more than sufficient.
It was conducted in the evening at around 7:00 p.m.
The hackerrank environment is clearly the best for conducting coding exams as it provides a decent interface for debugging and testing purposes.
There were 3 questions- 1 of easy level and 2 of medium level.
The round was conducted on CodePair platform which provides a IDE along with a video call for interviews.
There were 2 interviewers and both were friendly.
I was first asked about the various subjects I have studied in my curriculum. Then I was asked about my favourite programming language to which I answered Python.
After this, they asked various confusing questions based on function calling, argument passing and pass by object reference concept in Python.
Then they asked about the implementation of dictionary in Python and wanted me to design one with the help of lists(arrays) and optimize its search, add and delete operations. (Could be done with hashing and probing).
Then they asked questions from subjects like Computer Architecture and Theory of Computation (Basic questions were asked so you should just remember the key topics in the subject).
