I'm a software professional with 15 years+ experience in software development as well as leadership. I'm currently an Engineering Manager at a mid-size startup. I've been using LC on/off for preparation however I find it is skewed primarily to Entry level or Intermediate SW roles.

My focus is more on taking the leadership path at Big Tech companies in the next 6 - 12 months. I seek some advice from the community on what should be the preparation strategy.
