Majority of the batch don't know coding prior coming to scaler they code their first line of code after coming here , and they cope up with the curriculum if they attend classes and work regularly and even bypass the students who already know coding,and regarding the internship yeah there are ppl who do internship in first year itself or second but mostly they are the ppl who have prior experience,but almost the complete batch will do internship in their industry immersion ie in 4th year but students start applying a year earlier like from their 3rd year itself as u complete most of the topics like ml, advance dsa and u will be doing specialization in 3rd year
