How does one prepare for Amazon lab126 firmware/embedded position phone screen. How many questions are generally asked? Are they leetcode easy/medium?

At this stage do I need to prepare for behavioral questions too?

    You cannot leetcode for embedded systems. All those recursive and dynamic programming stuff will fall flat when the system run out of resource.

      Data structures needed for embedded: arrays and linked lists. Everything else is fancy.

    I had an interview with them 5-6 years ago. Had two phone screens. First one was relatively easy (reverse string and etc). The second one was much more involved. The guy started from bare metal (caches, pipelines, mmu, etc) and took me all the way up in the stack until I broke down 😂

      Second that. My career is still under water for having that purgatory on my resume. Almost seems like I need to go get my complete ID changed to stand a chance at getting an interview call from MAGA

      I have never worked at a FANG company. I feel like people respect you a lot more if you have a brand on your resume. Is the culture really that bad? I am quite happy where I am, but want a brand name.

      @amz1 AMZN bought that place on a fire sale a few years ago when I started. Give u context nobody that I worked with back from 2014 survived there for more than a year. But few cockroaches who did survive ended up in Google. So if u can make it through the circus of a interview, then u have a chance.

    OP
    Yeah agreed. I mostly want to practice bit manipulation, linked lists, queues and stacks and bit of trees. Did about 70 mediums so far.
