Tree traversal under pressure

Return a binary tree in level order. Compare an iterative queue with recursion and test an empty tree and a long chain.

What a strong answer demonstrates

A correct traversal, bounded auxiliary memory, and a clear explanation of the trade-off.

0230 min suggested

What people at Apple say

Reviews originally posted on Glassdoor.

Working at Apple can prove to be immensely helpful when it comes to earning the right kind of exposure,salary packages and also a work-pay balance. We need to cater the locals with their local flavour,keeps your prices competetive ,value their diverse cultures,not to hurt sentiments,privide understanding services,and lot more things. One of the keys to successful upward communication is to empgasize outcomes rather than processes and background details. Intense preperation and practice will make you confident,but confidence and a big smile aren't always enough.
Must create your own work/life balance Constant reorganization & personnel shuffling impacts productivity DIY engineering culture, little to no mentoring Tiny teams with huge impact. It's a real challenge to stay a motivated engineer in a culture where the majority of new projects are killed off, resulting in constant outflow of engineering talent. Finding ways to keep engineer engagement & retention higher should be a top priority.
Supportive manager, interesting problems, competitive salary, and about everyone is dedicated to the product. Truly first class coworkers and the culture within my org was supportive. I could really focus on the work in a way I couldn't at other larger companies and I knew that my contribution was amounting to an important impact for users. The skills I learned here have translated forward to other jobs I have had afterwards and I am certain I am a better engineer for having spent time here.
There were good opportunities and some cool technologies. Teams are in general awesome. Communications and desire to build a great product is evident throughout engineers. Leadership is lacking over the years. More and more emphasis are being placed on political influencing instead of focusing on the technology. Company used it’s large presence to bully individuals with disabilities especially veterans. Learn to refocus back on product driven innovation. Respect for ADA and veterans with disabilities. Similar to the respect Apple likes to emphasize with regards to their political beliefs.
Working at Apple means that the things you work on get into the hands of hundreds of millions of people, literally. It's a lot of pressure to get things right and drives one to do the best work of their lives. 2+ years later I'm still blown away by the talent and creativity of people I work with. It's a lot of work, teams are usually strapped for resources and under pressure to deliver on strict timelines leading to high stress and long hours at certain times during the year.
