Software Engineer Interview Questions

I Software engineer scrivono i programmi per progettare e sviluppare software informatici. I colloqui sono prettamente tecnici, quindi preparati ad affrontare problemi di programmazione e rompicapi matematici. Le domande specifiche che ti saranno poste dipenderanno dal tipo di posizione che stai cercando nell'ambito della programmazione. Prova a fare le dovute ricerche su una disciplina software specifica, come lo sviluppo si siti web, di applicazioni o di sistemi.

Domande tipiche dei colloqui per Software engineer e come rispondere

Question 1

Domanda 1: Come descriveresti il tuo processo di programmazione?

How to answer
Come rispondere: Nel rispondere a una domanda sul processo o ciclo di vita per lo sviluppo e la progettazione di un software, è utile descrivere tutti i passaggi, a partire dall'ottenimento dei requisiti per il prodotto finale. Includi quanti più dettagli possibile per dare all'intervistatore maggiori informazioni su eventuali lavori svolti in qualità di Software engineer e su come hai gestito gli incarichi, così da dimostrare che sei in grado di affrontare un progetto dall'inizio alla fine.
Question 2

Domanda 2: Quali linguaggi di programmazione conosci e preferisci?

How to answer
Come rispondere: L'intervistatore vuole sapere quali linguaggi di programmazione conosci meglio e quali preferisci. Non esiste una risposta giusta o sbagliata a questa domanda, il cui scopo è invece ottenere informazioni approfondite sulle tue capacità e competenze di programmazione. Se nell'offerta di lavoro per la quale ti stai candidando sono indicate preferenze per dei linguaggi specifici, menzionali quando parli dei linguaggi software che conosci.
Question 3

Domanda 3: Parlami di un progetto che hai portato a termine con successo.

How to answer
Come rispondere: Nel descrivere un progetto che hai portato a termine con successo, è utile individuare gli aspetti che hanno funzionato e descrivere in dettaglio i diversi elementi delle attività svolte. Puoi descrivere il team con il quale hai lavorato, il modo in cui hai gestito i tempi e il contributo specifico che hai apportato.

There were 2 questions I tackled. The first was a power function that needed to be implemented in logn time and a Java encapsulation question (asking questions about making arrays inaccessible from outside the object).

There is only one coding problem given 100min. The problem is as below: A group of farmers has some elevation data, and we’re going to help them understand how rainfall flows over their farmland. We’ll represent the land as a two-dimensional array of altitudes and use the following model, based on the idea that water flows downhill: If a cell’s four neighboring cells all have higher altitudes, we call this cell a sink; water collects in sinks. Otherwise, water will flow to the neighboring cell with the lowest altitude. If a cell is not a sink, you may assume it has a unique lowest neighbor and that this neighbor will be lower than the cell. Cells that drain into the same sink – directly or indirectly – are said to be part of the same basin. Your challenge is to partition the map into basins. In particular, given a map of elevations, your code should partition the map into basins and output the sizes of the basins, in descending order. Assume the elevation maps are square. Input will begin with a line with one integer, S, the height (and width) of the map. The next S lines will each contain a row of the map, each with S integers – the elevations of the S cells in the row. Some farmers have small land plots such as the examples below, while some have larger plots. However, in no case will a farmer have a plot of land larger than S = 1000. Note: The input uses unix line endings (\n). If you try to view the sample inputs on a windows machine with a program that does not convert line endings (like Notepad), you will see the input appear all on a single line. Your code should output a space-separated list of the basin sizes, in descending order. (Trailing spaces are ignored.) While correctness and performance are the most important parts of this problem, a human will be reading your solution, so please make an effort to submit clean, readable code. In particular, do not write code as if you were solving a problem for a competition. A few examples are below. Input: 3 1 5 2 2 4 7 3 6 9 Output: 7 2 The basins, labeled with A’s and B’s, are: A A B A A B A A A Input: 1 10 Output: 1 There is only one basin in this case. Input: 5 1 0 2 5 8 2 3 4 7 9 3 5 7 8 9 1 2 5 4 3 3 3 5 2 1 Output: 11 7 7 The basins, labeled with A’s, B’s, and C’s, are: A A A A A A A A A A B B A C C B B B C C B B C C C Input: 4 0 2 1 3 2 1 0 4 3 3 3 3 5 5 2 1 Output: 7 5 4 The basins, labeled with A’s, B’s, and C’s, are: A A B B A B B B A B B C A C C C

Classix 2 eggs problem . * You are given 2 eggs. * You have access to a 100-storey building. * Eggs can be very hard or very fragile means it may break if dropped from the first floor or may not even break if dropped from 100 th floor.Both eggs are identical. * You need to figure out the highest floor of a 100-storey building an egg can be dropped without breaking. * Now the question is how many drops you need to make. You are allowed to break 2 eggs in the process
