Here’s something nobody tells you in interview feedback: "The candidate used excessive filler words" doesn’t appear on the scorecard. It shows up as "lacked confidence" or "communication could be stronger" or "not sure about leadership presence."
Filler words don’t get called out directly. They get penalised indirectly.
Why "basically" is the worst one
Every language community has its default fillers. For Indian English speakers, "basically" is the big one. Followed by "actually," "you know," "so," and "like."
"Basically" is particularly damaging because it implies simplification. When you say "So basically what happened was..." you’re unconsciously signalling that you’re about to oversimplify. Say it enough times and the interviewer subconsciously registers: this person isn’t precise.
In a FAANG interview where precision and clarity are explicitly evaluated, that’s a problem.
How many is too many?
In natural speech, 1-2 filler words per minute is normal and barely noticeable. Most native English speakers hit this rate without thinking about it.
Indian engineers in interview settings typically hit 6-10 per minute. Some go higher. At that frequency, fillers become the dominant pattern the interviewer hears.
Record yourself answering a behavioural question for two minutes. Count the fillers. If you’re above 3 per minute, it’s affecting your interviews.
Why you do it
Filler words serve a purpose. They hold your speaking turn. They buy time while your brain formulates the next thought. They smooth transitions between ideas.
The problem is that in a high-pressure interview, your filler rate spikes. The more nervous you are, the more fillers you produce. And the more fillers you produce, the less confident you sound, which makes you more nervous.
It’s a feedback loop.
The replacement: confident silence
The fix is not to speak faster to eliminate gaps. The fix is to replace filler words with silence.
A one-second pause between sentences sounds confident. It sounds deliberate. It sounds like someone who thinks before they speak.
"Basically, so, what happened was, actually, we had this situation where basically the database was..."
versus
"We had a database failure during peak traffic. [pause] I led the incident response. [pause] Here’s what we did."
Same information. Completely different impression.
The drill that works
This is the single most effective exercise for reducing filler words:
1. Set a timer for 2 minutes.
2. Pick any topic (your last project, your morning routine, a movie you watched).
3. Talk about it continuously for 2 minutes.
4. Every time you catch yourself using a filler, stop mid-sentence. Pause for one full second. Then continue.
Do this once a day for two weeks. Your filler rate will drop by 60-70%.
The first few days feel brutal. You’ll stop every 10 seconds. That’s the point. You’re building awareness of a habit that’s currently invisible to you.
The physical anchor
Fillers often come from physical tension. Your chest tightens, your breathing gets shallow, and filler words rush in to fill the space.
Before your interview:
- Plant both feet flat on the floor.
- Rest your hands on the desk or your lap.
- Take three slow breaths: 4 seconds in, 4 seconds hold, 4 seconds out.
During the interview, when you feel a filler coming:
- Press your feet into the floor.
- Take a breath.
- Start the sentence.
This sounds simple because it is. The difficulty is remembering to do it when you’re nervous.
The timeline
Most people see a significant reduction in filler words within 2-3 weeks of daily practice. Complete elimination isn’t the goal and isn’t natural. Getting from 8 per minute to 2 per minute is the goal. At that level, they’re invisible to the interviewer.
The engineers who improve fastest are the ones who record themselves and listen back. Hearing your own fillers is uncomfortable. That discomfort is the mechanism of change.
