The response can be two words or two paragraphs. Some examples of open-ended questions are shown below. Open-ended interview questions allow the respondent open options for responding. The examples were selected from different interviews and are not shown in any particular order.
As you can see, there are several advantages to using open-ended questions. There are, however, also many drawbacks:. The alternative to open-ended questions is found in the other basic question type: closed questions. A closed question limits the response available to the interviewee. You may be familiar with closed questions through multiple-choice exams in college. You are given a question and five responses, but you are not allowed to write down your own response and still be counted as having correctly answered the question.
A special kind of closed question is the bipolar question. A file descriptor is a data structure used by a program to get a handle on a file. The most commonly known are:. Even though a file is open, it might not have a file descriptor associated with it such as current working directories, memory mapped files and executable text files.
Nonetheless, at times interviewers may press students or ask questions that are uncomfortable. Interviewers do this in the belief that such questions are ones the student should be prepared to answer. Closed File Some medical school interviews are "closed file," which means the interviewer has been given the student's name and perhaps personal statement, but nothing more. In this case, the idea is for the interviewer to come in with few preconceptions and to develop impressions of the student based almost exclusively on the interview.
Open File "Open file" interviews presumably have the opposite premise: the interviewer knows a lot about the student on paper and seeks confirmation of his or her written self-representation during the course of the interview. While open file interviews may sometimes work this way, it is also not unusual to find that interviewers have not always found an opportunity to review the student's file; in such cases, the interview is in effect a closed file interview.
Generally speaking, this means being reasonably explicit about one's activities and achievements, anchoring them in time and place. Before the Interview Part of the purpose of the mock interview is to simulate a medical school interview. Students should:. Interview Process Students will be interviewed by an "unassigned" prehealth advisor, and should be prepared for questions that may address the following issues:.
The MMI is a screening technique that purports to scientifically assess your suitability for the medical profession by inviting many judges to form an estimate of your character. In the MMI process, speed rules the day. Instead of inviting you to converse at length with a single interviewer as the conventional interview does , the MMI gives you the chance to speak briefly, with many different interlocutors about many distinct subjects. It places you before a succession of examiners, one at a time, as you pass among the adjoining rooms in a classroom building or clinic.
A number of American medical schools have adopted the MMI format for their interviews. Currently, schools that utilize the MMI include:. Main navigation expanded Admissions. Educational Financing. Parquet is a column format file supported by many data processing systems. Spark SQL facilitates us to perform both read and write operations with the Parquet file. Apache Spark is an open-source analytics and processing engine for large-scale data processing, but it does not have any storage engine.
Apache Spark itself provides a versatile machine learning library called MLif. By using this library, we can implement machine learning in Spark.
The main task of a Spark Engine is handling the process of scheduling, distributing and monitoring the data application across the clusters. The SparkContent is the entry point to Apache Spark. SparkContext facilitates users to create RDDs, which provide various ways of churning data. In SparkSQL, real-time data processing is not possible directly. Akka is used for scheduling in Apache Spark. Spark also uses Akka for messaging between the workers and masters. In Apache Spark, the Parquet file is used to perform both read and write operations.
Following is the list of some advantages of having a Parquet file:. In Apache Spark, the persist function is used to allow the user to specify the storage level, whereas the cache function uses the default storage level. Tachyon is the Apache Spark library's name, which is used for reliable file sharing at memory speed across various cluster frameworks. In Apache Spark, shuffling is the process of redistributing data across partitions that may lead to data movement across the executors.
The implementation of shuffle operation is entirely different in Spark as compared to Hadoop. Its execution is the result of all previously created transformations. Yarn is one of the most important features of Apache Spark. Apache Spark is an in-memory distributed data processing engine, and YARN is a cluster management technology that is used to run Spark. Yarn makes you able to dynamically share and centrally configure the same pool of cluster resources between all frameworks that run on Yarn.
When Spark runs on Yarn, it makes the binary distribution as it is built on Yarn support. Apache Spark is the best fit for simple machine learning algorithms like clustering, regression, and classification, etc. In Apache Spark, checkpoints are used to allow the program to run all around the clock.
It also helps to make it resilient towards failure irrespective of application logic. In Apache Spark, when a transformation map or filter etc. This lineage is used to keep track of what all transformations have to be applied on that RDD. It also traces the location from where it has to read the data. It specifies that all the dependencies between the RDD are recorded in a graph rather than the original data. You can trigger the clean-ups by setting the parameter ' Spark.
Yes, you can run all kinds of spark jobs inside MapReduce without the need to obtain the admin rights of that application. BlinkDB is a query engine tool used to execute SQL queries on massive volumes of data and renders query results in the meaningful error bars.
Because of having a web-based user interface, Spark can handle monitoring and logging in standalone mode. JavaTpoint offers too many high quality services.

Following is a list of few things which are better in Apache Spark: Apache Spark keeps the cache data in memory, which is beneficial in iterative algorithms and can easily be used in machine learning. Apache Spark is easy to use as it knows how to operate on data. It supports SQL queries, streaming data as well as graph data processing.
Spark doesn't need Hadoop to run. It can run on its own using other storages like Cassandra, S3, from which Spark can read and write. Apache Spark's speed is very high as it can run programs up to times faster in-memory or ten times faster on disk than MapReduce. MapReduce can process data in batches only. Speed: The processing speed of Apache Spark is extremely high.
It runs almost times faster than Hadoop MapReduce.
