is a comprehensive book on getting a job at a top tech company, while focuses on dev interviews and does this for PMs.
CareerCup's interview videos give you a real-life look at technical interviews. In these unscripted videos, watch how other candidates handle tough questions and how the interviewer thinks about their performance.
Most engineers make critical mistakes on their resumes -- we can fix your resume with our custom resume review service. And, we use fellow engineers as our resume reviewers, so you can be sure that we "get" what you're saying.
Our Mock Interviews will be conducted "in character" just like a real interview, and can focus on whatever topics you want. All our interviewers have worked for Microsoft, Google or Amazon, you know you'll get a true-to-life experience.
Limited network bandwidth and fixed browsers means we have to optimize the efficiency of how the browser and phone connect to the data center. If we cannot change any aspect of the browser, and we cannot expand the bandwidth, we probably should focus on handling the load better.
- Javeed April 23, 2015You can do any of the following:
1. Improve the algorithm handling bandwidth distribution from wireless cells to support a more dynamic structure permitting users to aquire more of the available bandwidth inversely proportional to the demand.
2. Improve the data center's ability to process incoming requests, possibly increasing its caching size, the number of parallel processors running, improving the connection hardware to raise transfer speed, or even refine the relay setup to optimize the transfers between the deployed wireless cells and the center.
3. On the phone, you can obviously upgrade all the hardware, affording more memory to browser, additionally a upgrade to the wireless component to allow for multithreading of connections or maybe synchronizing with local cells to improve quality.
4. Alter the phones thread scheduler to always prioritize the browser and the connection requests above anything else. (not the smartest move but it would certainly mean less delays on usage of the browser)
5. Prevent the installation of addons and plugins for the browser in the phones os or optimize for the specific browsers
6. add a ethernet port to the phone because no one said the connection has to be wireless all the time.
7. Have several thousand support techs or use a automation program to manage the networks allocation of bandwidth and priority.
This is, of course, all speculation. Rather nebulous question.
