Machine learning engineer sollicitatievragen

Bedrijven vertrouwen op machine learning engineers voor het ontwerpen en verbeteren van systemen waarmee hun software zichzelf kan verbeteren, in plaats van dat deze specifiek wordt geprogrammeerd. Tijdens een sollicitatiegesprek kunt u flink worden getest op uw kennis van computerwetenschappen en gegevenswetenschappen, met de nadruk op het herkennen van patronen en trends. Een bachelor in computerwetenschappen of een gerelateerd vakgebied is vereist.

Meest gestelde sollicitatievragen voor een machine learning engineer (M/V/X) en hoe te antwoorden

Tips om deze drie veelgestelde sollicitatievragen voor een machine learning engineer te beantwoorden:

Vraag 1: Wat zijn de belangrijkste algoritmen, programmeertermen en theorieën die u moet begrijpen als machine learning engineer?

Zo antwoordt u: Bereid u voor op het praten over zaken als Type I- en Type II-fouten, supervised en unsupervised machine learning, ROC-curves en andere belangrijke onderdelen van machine learning. Werkgevers willen weten of u veel kennis hebt van de technische aspecten van de functie.

Vraag 2: Hoe zou u machine learning uitleggen aan iemand die het niet begrijpt?

Zo antwoordt u: Soms moeten machine learning engineers werken met mensen die niet bekend zijn met de technische aspecten van de functie. Gebruik deze sollicitatievraag als een kans om uw grote kennis van de functie en uw communicatieve vaardigheden te laten zien.

Vraag 3: Hoe blijft u op de hoogte van het laatste nieuws en trends in machine learning?

Zo antwoordt u: Door te vertellen over hoe u op de hoogte blijft van het laatste nieuws en trends in machine learning laat u een werkgever zien dat u betrokken bent bij de branche, een vaardig onderzoeker bent en over zelfmotivatie beschikt.

Suppose you have a matrix of numbers. How can you easily compute the sum of any rectangle (i.e. a range [row_start, row_end, col_start, col_end]) of those numbers? How would you code this?

7 antwoorden

Compute the sum of the rectangles, for all i,j, bounded by (i,j), (i,m), (n,j), (n,m), where (n,m) is the size of the matrix M. Call that sum s(i,j). You can calculate s(i,j) by dynamic programming: s(i,j) = M(i,j) + s(i+1,j) + s(i,j+1) - s(i+1,j+1). And the sum of any rectangle can be computed from s(i,j). Minder

Awesome!!

The answer is already popular in computer vision fields!! It is called integral imaging. See this page http://en.wikipedia.org/wiki/Haar-like_features Minder

What were the online coding questions like? Could you elaborate?

Object detection. Is that what yours was?

it is same as mine. Could you give me more details about the online coding? what algorithm did they test on object detection part? Minder

Do you mind to share what are the hard leetcode questions they asked during the interview? Minder

I dont think it's fair to share which question they asked. But the exact same question is on leetcode and the difficulty level is hard. Minder

What topic you are being ask from in leetcode? also did they ask you system design and CS fundamentals. Minder

how to sort in O(Logn) time

3 antwoorden

I don't think you can sort in O(logn) because you will need to go through the whole data at least once, making it O(n). Indeed, you can do it in O(logn) if the data is guarantee with some specific constrain or relationship. I think the best you can sort a completely random data is O(nlogn). Minder

I didn't come up with the answer. it is not difficult, just not prepared

1 question I had was next greatest element in an array - searching only to the right. I had a solution with O(n^2), but they said don't even bother, that's rejected

3 antwoorden

If you do it backwards, you actually just need to compare the last greatest value against the next element, so should be o(n) Minder

Just use monotonic stack , it will help to get the next greatest element for every element of the array on O(n) with a space of o(n) Minder

O(n^2) solution rejected, then tried reverse search, but ran out of time

Design round: Design an api rate limiter Coding round: simple manipulation of arrays and maps Craft round: Design an ML Labelling system

3 antwoorden

There will be many documents in a document database. The labelling system must use machine learning to label into different categories. Eg help desk, system document, technical. There will a small train dataset available but not entirely reliable. Minder

The correct answer would be to use a combination of weak learning methods and gradually incorporate feedback and make it stronger Minder

APi rate limiter was really simple, just look at uber/ratelimit on git and thats it. Rest was farily easy Minder

Why does one use MSE as a measure of quality. What is the scientific/mathematical reason for the same?

3 antwoorden

Mean-Square error is an error metric for measuring image or video quality it is popular video and image quality metric because the analysis and mathematics is easier with this L2-Norm metric. Most video and image quality experts will agree that MSE is not a very good measure of perceptual video and image quality. Minder

The mathematical reasoning behind the MSE is as follows: For any real applications, noise in the readings or the labels is inevitable. We generally assume this noise follows Gaussian distribution and this holds perfectly well for most of the real applications. Considering 'e' follows gaussian distribution in y=f(x) + e and calculating the MLE, we get MSE which is also L2 distance. Note: Assuming some other noise distribution may lead to other MLE estimate which will not be MSE. Minder

MSE is used for understanding the weight of the errors in any model. This helps us understand model accuracy in a way that is helpful when choosing different types of models. Check out more answers on InterviewQuery.com Minder
