Adaface Machine Learning Assessment Test is the most accurate way to shortlist Machine Learning Engineers



Reason #1

Tests for on-the-job skills

The Machine Learning Assessment Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates.

The pre-employment machine learning assessment test screens candidates for the typical skills recruiters look for Machine Learning developer roles:

  • Experience designing, developing, and researching Machine Learning models
  • Deep understanding of fundamental data structures and data modeling
  • Expertise in math, probability and statistics
  • Ability to write robust code
  • Experience with machine learning frameworks (like Keras, PyTorch, Tensorflow etc.) and libraries (like scikit-learn, Numpy, Pandas etc.)
  • Ability to choose hardware for running an ML model with the needed latency

The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for Machine Learning developer roles. Anti-cheating features enable you to be comfortable with conducting assessments online. The Machine Learning Assessment Test is ideal for helping recruiters identify which candidates have the skills to do well on the job.

Reason #2

No trick questions

no trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface ->
Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

These are just a small sample from our library of 10,000+ questions. The actual questions on this Machine Learning Assessment Test will be non-googleable.

D: max_depth=None, min_samples_split=2, min_samples_leaf=1
E: max_depth=3, min_samples_split=10, min_samples_leaf=10
F; max_depth=5, min_samples_split=5, min_samples_leaf=5

Medium

n-gram generator
Solve
Our newest machine learning developer want to write a function to calculate the n-gram of any text. An N-gram means a sequence of N words. So for example, "black cats" is a 2-gram, "saw black cats" is a 3-gram etc. The 2-gram of the sentence "the big bad wolf fell down" would be [["the", "big"], ["big", "bad"], ["bad", "wolf"], ["wolf", "fell"], ["fell", "down"]]. Can you help them select the correct function for the same?

Confusion Matrix
Model Evaluation
Solve
You have trained a supervised learning model to classify customer reviews as either "positive" or "negative" based on a dataset with 10,000 samples and 35 features, including the review text, reviewer's name, and rating. The dataset is split into a 7,000-sample training set and a 3,000-sample test set.

After training the model, you evaluate its performance using a confusion matrix on the test set, which shows the following results:

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Machine Learning Assessment Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Machine Learning Assessment Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

About Machine Learning Developer Roles

Machine learning (ML) is a subset of artificial intelligence (AI) that enables software programmes to grow increasingly effective at predicting outcomes without explicitly programming them to do so. Machine learning algorithms estimate new output values by using past data as input.

A machine learning (ML) developer is an expert in training models with data. Following that, the models are utilised to automate activities such as image classification, speech recognition, and market forecasting.

A machine learning developer creates a solution that is unique to each situation. The only way to get the best results is to thoroughly process the data and use the appropriate algorithm for the current situation.

Typical Machine Learning Developer/Engineer responsibilities include:

  • Understanding corporate objectives and creating models to assist them be accomplished, as well as measurements to track their success
  • Managing available resources such as hardware, data, and staff in order to meet deadlines
  • Analyzing the ML algorithms that may be utilised to tackle a particular problem and evaluating them based on their likelihood of success
  • Exploring and visualising data
  • Verifying and/or assuring data quality through data cleansing
  • Locating public datasets that might be utilised for training
  • Developing Validation Methodologies
  • Specifying the preprocessing or feature engineering that will be performed on a given dataset
  • Creating pipelines for data augmentation
  • Analyzing the model's flaws and devising solutions to overcome them

Machine Learning Online Test FAQs

Vilken typ av frågor inkluderar maskininlärningstestet?

Detta testprov för maskininlärning av maskiner består av scenariebaserade frågor som kräver att kandidater visar deras förmåga att:

  • Förbered data för maskininlärningsalgoritmer
  • Använd ML -algoritmer som logistisk regression, stödvektormaskiner, beslutsträd och slumpmässiga skogar för klassificering
  • Bygg klusteralgoritmer
  • föreslå den mest lämpliga algoritmen för ett specifikt användningsfall
  • Uppskatta prestanda för inlärningsalgoritmer

Kan detta test eller utvärdering användas för roller för äldre maskininlärningstekniker?

För seniormaskininlärningsingenjörer kan du begära ett anpassat test. Inom 48 timmar kommer våra ämnesexperter att anpassa bedömningen i enlighet med din arbetsbeskrivning och senioritetsnivå. Ett typiskt test för äldre roller, förutom grundläggande faktorer, kommer testet att fokusera på att testa en kandidats förmåga att:

  • Struktur ML -projekt
  • Identifiera brister i olika maskininlärningsalgoritmer
  • Designa en datastrengöring och datamärkningsprocess
  • Välj rätt utvärderingsmetriker för att förbättra modellprestanda
  • Utvärdera effekterna av hårdvaruprestanda på maskininlärningsalgoritmerna

Kan jag kombinera flera färdigheter till en anpassad bedömning?

Ja absolut. Anpassade bedömningar ställs in baserat på din arbetsbeskrivning och kommer att innehålla frågor om alla måste-ha färdigheter du anger.

Har du några anti-cheating eller proctoring-funktioner på plats?

Vi har följande anti-cheating-funktioner på plats:

  • Icke-Googleable-frågor
  • IP -proctoring
  • webbproctoring
  • webbkamera proctoring
  • Detektion av plagiering
  • säker webbläsare

Läs mer om proctoring -funktionerna.

Hur tolkar jag testresultat?

Det främsta att tänka på är att en bedömning är ett eliminationsverktyg, inte ett urvalsverktyg. En kompetensbedömning är optimerad för att hjälpa dig att eliminera kandidater som inte är tekniskt kvalificerade för rollen, den är inte optimerad för att hjälpa dig hitta den bästa kandidaten för rollen. Så det ideala sättet att använda en bedömning är att bestämma en tröskelpoäng (vanligtvis 55%, vi hjälper dig att jämföra) och bjuda in alla kandidater som gör poäng över tröskeln för nästa intervjurundor.

Vilken erfarenhetsnivå kan jag använda detta test för?

Varje AdaFace -bedömning anpassas till din arbetsbeskrivning/ idealisk kandidatperson (våra ämnesexperter kommer att välja rätt frågor för din bedömning från vårt bibliotek med 10000+ frågor). Denna bedömning kan anpassas för alla erfarenhetsnivåer.

Får varje kandidat samma frågor?

Ja, det gör det mycket lättare för dig att jämföra kandidater. Alternativ för MCQ -frågor och ordningen på frågor randomiseras. Vi har anti-cheating/proctoring -funktioner på plats. I vår företagsplan har vi också möjlighet att skapa flera versioner av samma bedömning med frågor om liknande svårighetsnivåer.

Jag är kandidat. Kan jag prova ett träningstest?

Nej. Tyvärr stöder vi inte övningstester just nu. Du kan dock använda våra exempelfrågor för övning.

Vad är kostnaden för att använda detta test?

Du kan kolla in våra prisplaner.

Kan jag få en gratis provperiod?

Plattformen är helt självbetjänande, så här är ett sätt att gå vidare:

  • Du kan registrera dig gratis för att få en känsla för hur det fungerar.
  • Den kostnadsfria provperioden inkluderar en provbedömning (Java/JavaScript) som du hittar i din instrumentpanel när du registrerar dig. Du kan använda den för att granska kvaliteten på frågorna och kandidaternas upplevelse av ett konversationstest på Adaface.
  • För att granska kvaliteten på frågorna kan du också granska våra offentliga frågor för 50+ färdigheter här.
