• Two easy-level LeetCode questions.

Round 3 (HR Round): This round involved questions about the candidate's resume and their motivation to join LG. The HR representative also discussed the compensation package and other benefits. Although the candidate was initially told there might be another round, an offer letter was extended without further interviews.
