There is no point in worrying about python being a good choice for coding interview. Your clarity of understanding the basics concepts of any programming language is very important. It doesn’t matter whether you code in C,C++,Java, etc. What matters is how strong are your basic concepts like Data Structures and Algorithms. The way you solve a problem and your approach is mainly seen. So work on it rather than worrying about the choice of Programming language.
Hope it helps
All d very best.
