Production Engineer Interview Questions in United States
"When interviewing to be a production engineer, you will likely be asked many technical questions about your understanding of manufacturing processes. Interviewers will want to determine whether you will be able to find ways to improve their production processes, whether that be through increasing safety, reducing waste, or increasing output. They will also be concerned about your ability to simplify the explanation of complicated processes to workers and managers who do not have the same education in engineering as you do. Production engineers are required to have at least a bachelor's degree in engineering."
Details of Artificial lift technology I had experience with. how to design one?
1 Answers↳
System support for Artificial lift technology, are: 1. Expert System: the more data is used increasingly smaller errors displayed on the executive summary report. 2. Fuzzy Logic: System will assign frequently used data or show up and can be used as a parameter for controlling the calculation and time in the system. 3. Neuro Network: as a distribution to support decisions related to the unit automatically generated from the Expert System and Fuzzy Logic. Thankyou, Less

Make sure to highlight your ability to identity a priority problem, take initiative, and deliver an effective solution. Remember that you don't always have to solve problems alone - knowing how to seek out helpful assistance is a useful skill. Less
Only one tech question that wasn't a brain teaser- technical job related question was about line balance. There's 3 tools in a row with known stabilities. You know the second tool is very unstable but you need to meet demand.

For a given set of software checkins, write a program that will determine which part along the branch where the fault lies.
5 Answers↳
A - array of versions, |A| = n check(A[0]) = true - first version is fine check(A[n-1]) = false - last version has the fault binary search: int start = 0; int end = n-1; while(end-start>1){ int middle = (end+start)/2; if (check(A[middle])) start = middle; else end = middle; } A[end] is the version with the fault Less

first, design a test case to detect the failure. next, determine the last known "good" state of the software, i.e. the revision number of the last known "good" state. now, write a script that will check out each subsequent revision starting from the known good revision, build, run the test case and examine the output. When output fails, you can determine the revision at which the bug was introduced. Less
↳
I would write an integration test, for that scenario which started to fail. Then I'd write a shell script which would run that test over some amount of last revisions. Once test is failed, you've found a revision where mistake was made. Less

What options do you have, nefarious or otherwise, to stop people on a wireless network you are also on (but have no admin rights to) from hogging bandwidth by streaming videos?

This question is basically a way of ascertaining how much knowledge you have of the effect of distorting networking protocols in nonstandard ways. Everything from "ask them politely to stop" to "hijack their connection". Less

Why wouldn't you want a root DNS server to answer queries for you, instead of delegating you to an authoritative server?
4 Answers↳
Because root DNS server can't handle zillions of requests at once, that's why you need a load balancer to split tasks on multiple DNS servers. every server has it's own limits, and load balancing helps to "scale" the limits. Less
↳
because it would be faster due also to caching mechanism.
↳
DNS servers basically are text file doing Name to IP mapping(A type). So if a root server had to answer all the queries ,it would essentially be a million line text file, mapping each and every website.This would result in large CPU processing and time. Essentially, Root servers redirect the query to top level DNS servers and so on Less
