The full lesson, in text

Hello students, welcome to Kwickprep. Two students have the same marks, but only one gets the job. Often, the difference is communication. Today we will learn the communication process, its types, barriers, and how to write emails, speak in interviews and use a phone professionally.

Let us start with the meaning. Communication is the sharing of ideas, facts or feelings. It happens between two or more people. It is successful only when the receiver understands the message exactly as the sender meant it.

Communication follows a process with clear steps. First, the sender has an idea to share. The sender encodes it, which means putting it into words, pictures or signs. The message travels through a channel, such as a phone call or an email. The receiver decodes it, which means understanding its meaning. Finally, the receiver gives feedback, a reply that shows the message was understood.

Communication is of four main types. Oral verbal communication uses spoken words, like a meeting or a phone call. Written verbal communication uses written words, like an email or a report. Non verbal communication uses body language, facial expressions and tone of voice. Visual communication uses pictures, charts and graphs to explain ideas.

At work, we must choose between formal and informal communication. Formal communication is used with seniors, teachers and clients. Its language is polite and complete, while informal language is casual and short. A leave application is formal, while a chat with a friend is informal.

Good professional messages follow the seven Cs. Clear means one main idea, and concise means no extra words. Concrete means specific facts, and correct means no errors in facts or grammar. Coherent means the points connect logically. Complete means the receiver has everything needed to act. Courteous means polite and respectful.

Sometimes a message fails to reach correctly, because of barriers. Language barriers happen when the receiver does not know the words, or technical jargon is used. Physical barriers include noise or a poor mobile network. Emotional barriers include anger, fear or stress. Cultural barriers happen when people from different backgrounds read gestures or words differently.

Listening is half of communication, and the best form is active listening. Look at the speaker and let them finish without interrupting. Nod or say okay to show you are following. Ask questions if something is unclear. Finally, repeat the key point in your own words to confirm you understood.

Written communication at work is mostly email. The subject line tells the topic in a few words. The greeting is polite, such as Dear Mr Sharma. The body gives the purpose, reason and dates, in short paragraphs. The closing ends with a word like Regards, followed by your full name.

Let us check an email together. The subject line just says hi. The body says, sir plz give leave tmrw. There is no name at the end. Pause and find the mistakes. The subject is vague, the words are short forms, the date is missing, and the sender is unknown, so it breaks the seven Cs.

An interview tests your oral and non verbal communication together. Dress neatly and reach ten minutes early. Greet the interviewers politely, sit straight and keep eye contact. Answer clearly and honestly, and if you do not know something, say so. At the end, thank them for their time.

Many jobs now use phone and video calls, so they need manners too. Start by greeting the person and saying your name. Speak clearly, at a steady pace, from a quiet place. On a video call, mute yourself when you are not speaking. End politely, and send a short follow up message if any task was agreed.

Let us revise what we learned today. Communication moves from sender, through a message and a channel, to a receiver who gives feedback. It can be oral, written, non verbal or visual. Follow the seven Cs and remove barriers. Listen actively, without interrupting. And use formal, clear language in emails and interviews.
