Hey Varun!

Campus Placement or Recruitment  occurs when firms visit your college campus, interview students and employ applicants to work for them. These campus placements are coordinated by your college, which invites the firms to get the students recruited from their college. Campus Placements are held prior to the final test.

First, the companies provide presentations about their organisations. Students learn everything there is to know about the organisations, their hiring process, and the pay you can anticipate. Afterwards, the students would get to know about the credentials and other essential factors that organisations have set to hire students. Companies typically interview just those candidates who belong to a specific educational stream and then select from that stream. You are required to give an aptitude test for the company you have applied in. If you qualify in the exam, an interview round is conducted through which students are finalised.  You will receive an offer letter, if you pass the official interview. You will be provided instructions and  you will be informed about the joining process. You will also be informed of any other pertinent information.

Since you haven't mentioned the course which you are enrolled in, I would just state that you will get questions from your field and the job title for which you are applying. The questions varies according to the different fields. You should just keep in mind that you will be asked for your introduction and whatever you speak you should be aware about the topics that you introduce in your introduction. Be prepared to get questions on whatever you have said in your introduction whether it is your interest or qualifications. Speak confidently and appear confident. Practice your communication skills. If you're receiving education in a technical field, make sure you brush up on your technical abilities and knowledge. Continue to read and update your technical expertise. Present yourself in a way which will make you stand out from the rest. Tell some qualities you possess which are not so common among your peers. Also, in whatever field you are studying make sure to read current affairs pertaining to that field.

You may be asked questions like why do you want to apply in this company or what do you know about the company or why you should be hired or  your expectations from the company if you get selected and also whatever you may have said in the interview may be questioned and asked upon. You should also be prepared to answer on your strengths and weaknesses. Although you shouldn't add any negative quality. You may also be asked that where do you see yourself in four/ five years and so on. There is just one most important tip which is to be confident.

All the best!
