Can I ask where are you based? Generally speaking I haven't really encountered with leetcode or design pattern type of questions, but I was mostly interviewed by Tier 1 and 2 [1] companies, and for junior-mid positions, and I live in Denmark.
I am in the Eastern USA. Looking at remote positions mostly (USA). I have yet to have an interview loop that did not involve both system design and some "leetcode"-style code questions.
None have been as complex or bad as some make them out to be, but all have the potential to trip you up depending on the day.
