LG Ad Solutions interview questions

3 rounds This was back in the day of 2018. Idk how it is now 1st algo -> asked me merge sort, linked list reversal question 2nd system design -> all sorts of good/tough system design questions 3rd (only taken if they like you in first two): HR/Manager/Biggie round asking general questions

Mostly SQL, Python, Excel questions were asked. Nothing too difficult in the entire process. About 3 to 4 rounds total were conducted. The interviewer was polite and knowledgeable. They tested basic concepts and even gave hints to help.
