In this post, I am extending my last article which was about the written test preparation for the post of Jr. Executive (ATC) examination. Post written test results, the successful candidates (around three times of total vacancies in number) are called for a voice test and interview which is the last part of the selection process.
Let’s first understand the importance of a Job interview. It’s a tool used by an employer (or representative of employing organization) for the selection of desired employee(s). An interview is basically conducted to test the communication skills, presence of mind, and quick decision-making capability of the candidate.
Generally, Interviews are held in four cities viz. New Delhi (For Northern Region), Mumbai (Western region), Chennai (Southern Region), Kolkata (Eastern and NE Regions).
I will start with the Voice test as it precedes the interview.
Voice Test for Air Traffic Controller
On the day of the interview, first, you will have to undergo a voice test which is followed by an interview. A Voice test is mandatory for the post of ATC(Air Traffic Controller) as the job profile requires day to day basis interaction with Pilots as well as with various other ATC units. So the voice test is conducted to ensure that candidate has good English language speaking fluency and is not stammering. To check this, a printed page is given which is required to be read by the candidate. The page basically has some sample phraseology used by Pilots/ATC. This is just a cakewalk for the candidates with a clear voice.
EDIT: I have written an article on ‘How to prepare for Voice Test’. It has two sample Voice Test papers. You can read the article here:
- How to Prepare for AAI ATC Voice Test
- Important Questions/Answers for AAI ATC Interview
- Read and Share AAI ATC Interview Experiences
Note: Although, in your Interview letter it is mentioned that candidate will have an option to respond either in Hindi or English my advice is to keep your conversation in English only with the official conducting this test.
After the voice test, you will be asked to wait for your turn for the interview. Just relax during this waiting period and try not to pay attention to the candidates boasting of their academic background or no. of tests they have cleared. Remember that you all are in the same boat at that moment and no one is superior or inferior. Avoid negative thoughts as they may hamper your chances of getting selected.
Now let’s move to the interview round which is the final hurdle for you to be part of this prestigious profession.
Interview for Air Traffic Controller :
It will be a Panel interview where senior officials of AAI(Airport Authority of India) will be judging your knowledge and communication skills. Usually, the interview board consists of 4 to 5 panelists.
So can we cross this hurdle with ease? Yes, you can do it. Here are some important points you should consider during the interview:
- Respond to the questions in English only, it really helps.
- Do not be anxious during the interview, they can sense it. So be comfortable.
- Be yourself and do not try to bluff at all. In case you don’t know the answer, simply admit to it instead of giving a wrong answer.
- Sometimes they will ask you to describe one of the objects installed in the Interview room like a TV, Projector, etc. which is basically for testing your fluency in spoken English. So just read a bit about these objects.
- Try to make eye contact while answering the questions.
- Do not tell them that you have cleared some other PSU’s exam or are waiting for a joining letter; it will create a doubt in the mind of the interviewer about selecting you because no one wants to select a candidate who may leave the organization any time.
- Last but not the least, have a smile on your face; it is the best thing to have…even in trouble when you don’t know the answer!! But do remember that an excessive smile reflects nervousness and lack of confidence.
Edit: Memory Test: Short-term memory is very essential for an ATC Officer. So be ready for this test where the panelist will test your short-term memory. What they really do is each one of them will ask you one question one by one and you have to listen and remember all these questions, then you will be asked to answer all the questions in the same sequence as they were asked. So you will be required to remember 5 questions and their sequence and then answer accordingly.
Potential Questions/Topics for ATC Interview :
I am aware that you all must be waiting for the potential questions which are asked during the interview. The topics vary from the knowledge of working of ATC to the geography of the world. In this section, I will try to cover as many topics as possible. The questions/topics are as:
