Feeling a lack of confidence during an interview when you're not using your mother tongue is quite common. There are a few reasons why this happens:

1. Language Barriers: If you're not fluent in English (or the language of the interview), you might worry about making mistakes or not expressing yourself clearly. This can make you feel anxious or self-conscious.
2. Cultural Expectations: Sometimes, there's a perception that proficiency in English (or another dominant language) is a measure of competence or professionalism. This can create pressure to perform well in that language, even if it's not your strongest.
3. Fear of Miscommunication: You might be concerned about not being able to convey your ideas accurately or misunderstand questions, which can add to your anxiety.
4. Limited Practice: If you're less accustomed to speaking in a non-native language, you might not have had as much practice in responding to questions or discussing complex topics. This can impact your confidence.
5. Stress and Performance Pressure: Interviews can be stressful events, and when compounded by language difficulties, the stress can make it harder to perform at your best.

There is no shortcut to get rid of it. The only solution is to start learning it consistently. Learning English demands much practice. One-on-one online classes are super effective for working professionals to join from any part of the world.
