As you work through the problem, it is important to continually review the progress made in order to ensure that a logical approach is being taken. Additionally, it is important to be mindful of any assumptions being made and to evaluate the impact of these assumptions on the potential solution.
How do you prioritize tasks to manage time effectively?
When managing time effectively, it is important to first identify the tasks that need to be completed. Once the tasks have been identified, it is then important to assess the tasks in order to determine which tasks are the most important or time-sensitive. This assessment should also consider any dependencies that may exist between tasks. After prioritizing the tasks, it is important to create a plan for how the tasks will be completed in the most efficient manner. Additionally, it is beneficial to review and adjust the plan as needed in order to ensure that the tasks are completed in a timely manner.
How do you identify the root cause of an issue?
Identifying the root cause of an issue can be difficult, but is essential in order to ensure that the issue is properly addressed. To make this determination, it is important to first identify all of the possible causes of the issue. This can be done by breaking the problem down into smaller parts and examining each part individually. Once all of the possible causes have been identified, it is important to evaluate the evidence and to determine which cause is the most likely root cause. Additionally, it is important to be aware of any assumptions that may be influencing the determination and to consider other potential causes that have been overlooked.
What is your experience with algorithms?
Explain an algorithm you created and how it was used?
I recently created an algorithm to sort an array using the selection sort technique. The algorithm receives an array as an input and returns an array with the same elements but sorted in ascending order. This algorithm was used to organize a list of customers in a database according to their last names.
Describe an algorithm you found to be particularly difficult?
I found the Wagner-Whitin algorithm to be particularly challenging. The algorithm is used to determine the optimal production policy for a production facility with multiple products and limited resources. It is a dynamic programming algorithm that involves breaking down a problem into sub-problems and solving them recursively. Understanding the logic of the algorithm and debugging it was a difficult task.
How do you approach debugging an algorithm?
When debugging an algorithm, I first identify the expected output of the algorithm, and then compare it to the actual output. This helps me determine the location of possible errors. I then use a combination of techniques such as tracing, breakpoints, and logging to identify the root cause of the problem. Once the root cause of the problem is found, I then take the necessary steps to fix it.
