Speaking English, while a requirement, has more to do with how the applicant is communicating their ideas with the interviewer during the selection process than with just knowing grammar. The process reviews the applicant’s ability to interpret the message of a standard written-in-English newspaper report or a statement issued and convey it in their own ways, verbally or in writing.
There are three components that make it up: smoothness, flow and coherence. Smoothness defines your ability to pause, gesture, repeat and self-correct while speaking. Flow follows the crux of the matter being spoken while coherence implies the candidate’s ability to sound logical despite all the corrections and stutters that the candidate may utter.
Here is a guide on how you can perform better at interviews.

Staying Up to Date with Current Affairs

Speaking English properly is not a one day task. English as a language is used for communication, and it takes many days of practise, which can begin by reading newspapers to stay aware of the current events. Newspapers and financial columns focus on the banking jargon and are written in standard English, which helps the candidate understand how the terms are used in daily lingo. It is a two strikes at one throw situation.

Reading Habits

Reading newspapers can help in grasping the toils of the jargon, but to tackle conversational English, you must expand your reading horizon to other casual sources. Examples include reading comic books to understand the tone and the dialogue, reading editorials columns to see how the people of the world have presented their views, reading novels and other small pieces of writing like essays and short stories, interviews of key speakers—be it a sportsperson, an actor or a banking official; it all amounts to understanding conversational English. You may even attempt to speak with a friend in English.
The importance of reading can never be understated. It may even serve as a break from the possible monotony of you revising your syllabus. Additionally, it also improves your vocabulary. You come across words that compel you to check their meaning and their usage. Using them, while checking yourself to not be over the top, will enhance your passing the interview.

Listening Habits

Listen, but listen to key speakers and your conversations in English occasionally. Even though you may be learning to speak in English better only for the interview purpose, learning a skill or a language has its uses for a long time. Not only does listening to people speak in English improve your ability as a listener, it also helps you improve on your own speech and how you use words. In that vein, you may prefer listening to audiobooks by way of getting a command of English.

Notice about Tenses and Ignore Them

While casually reading and listening, learn the structure of the sentence and try to imitate it to understand how it’s being said and how it makes sense. This structure includes the tenses and the forms of speech, along with a lot of other grammar and styles. You can try to foray into the nitty-gritty of it but while speaking, on the day of the interview, it’s best to ignore and go with the flow of it.

Build Self-Esteem

You will not be able to speak fluently or even well if you don’t believe in yourself and believe that you can. Self assurance is very necessary to ace the interview because the focus is not on English; it is on how well you are able to convey what you know, think and believe in English and how well you’re presenting yourself for the job you are applying for.

Use Fillers

Words like ‘quite,’ ‘to be honest,’ ‘I mean,’ ‘actually,’ ‘the thing is,’ ‘well,’ etc. are all good words that you must feel free to use. Just don’t sugarcoat your words with useless phrases and words that you’re unfamiliar with, or attempt to fake an accent. Don’t talk in slang either.

Cracking an interview is possible because the interviewers are assessing your personality and disposition towards the job and the sector. Therefore, practise English—speaking, conversing, listening well before the day or months of the interview.
