We have all been there: you feel great about your interview, but then you get that “thanks, but no thanks” email. Sometimes, the difference between an offer and a rejection isn’t your experience—it’s how you communicate.
Even highly qualified professionals can let small, avoidable grammar mistakes slip into their answers. In this post, we’ll look at 5 common errors that can make you sound less confident and how to fix them before your next interview.
1. Mixing Up Present Perfect and Past Simple
Many students struggle with whether to say “I worked at X company” or “I have worked at X company.”
- The Rule: Use Past Simple for finished time periods (e.g., “I worked there in 2023”). Use Present Perfect for experiences that are still relevant to your current skills (e.g., “I have managed teams for over five years”).
2. Using “Me” Instead of “I” (and vice versa)
You might hear people say, “My boss asked my colleague and I to finish the report.” This is grammatically incorrect.
- The Fix: Take the other person out of the sentence. Would you say, “My boss asked I to finish…”? No! You would say, “My boss asked me to finish.” Therefore, it is: “My boss asked my colleague and me.”
3. Overusing Filler Words
Words like “um,” “like,” and “actually” are natural, but overusing them makes you sound unsure of yourself.
- The Strategy: Embrace the pause. If you need a second to think, take a breath instead of filling the silence. A two-second pause makes you look thoughtful and composed.
4. Misusing “Impact” as a Verb
In a professional setting, people often say, “This will impact the market.” While common in casual speech, many formal style guides prefer “influence” or “affect” for the verb form.
- The Pro-Tip: Use “impact” as a noun (e.g., “The project had a positive impact”) and “affect” or “influence” as the verb (e.g., “This decision will influence our strategy”).
5. Using Subject-Verb Disagreement
This often happens when we get nervous and speak too quickly. For example: “The group of clients are coming in today.”
- The Fix: The subject is “group” (singular), not “clients.” It should be: “The group of clients is coming in today.”
Final Thoughts
Communication is a skill, and like any other, it gets better with practice. Don’t worry about being perfect; focus on being clear, professional, and authentic.
