Hi

I recently started appearing for contests. I have appeared for 3 : Weekly 225, 226 and Biweekly 44. The ratings/rankings for none of these have been updated yet. Is there any minimum number of contests required to be eligible for this ?

Also, I needed some suggestions. I am looking for a SDE role & would appear for interviews in about a month's time. I started LC in around December and have solved around 300 problems till now but I have done them topic/category wise. So I basically had the hint of the data structure that has to be applied. Now to progress further & improve my problem solving skills, please let me know what are my options. I am new to Leetcode.
Should I take up LC monthly challenges ?
Should I do company wise interview questions ?

Thanks!
