Hi Rakshit. Yes, apart from mathematics coding skills are important for quant traders as well.
Quant traders must be familiar with data mining, research, analysis, and automated trading systems. They are often involved in high-frequency trading or algorithmic trading. A good understanding of at least one programming language is a must, and the more programs the candidate knows, the better. Quantitative Analysts sometimes can have not-so-good programming skills (but it is strictly necessary to be good in coding at least in R or VBA) but being amazing in math, finance and statistics, is enough.
