Softwareentwickler Interview Questions

Softwareentwickler sind besonders gefragt und diese Rolle kann auch sehr gute Verdienstmöglichkeiten und hohe Arbeitszufriedenheit bieten. Bei einem Vorstellungsgespräch für Softwareentwickler werden Ihnen wahrscheinlich Fragen zu Ihren Hard und Soft Skills sowie zum effizienten Projektmanagement gestellt.

Typische Bewerbungsfragen als Softwareentwickler (m/w/d) und wie Sie diese beantworten

Question 1

Frage 1: Welche Art von Softwareentwicklung betreiben Sie derzeit?

How to answer
So beantworten Sie die Frage: Betonen Sie bei der Antwort auf die Frage nach Ihren aktuellen Softwareentwicklungsprojekten die Programmiersprachen und den Technologie-Stack, die Sie nutzen. Anhand dieser Frage können Personalverantwortliche bestimmen, ob Sie die nötigen Kompetenzen für den Umgang mit der zu erwartenden Workload haben.
Question 2

Frage 2: Beschreiben Sie ein Entwicklungsproblem, das Sie hatten, und wie Sie es behoben haben.

How to answer
So beantworten Sie die Frage: Wenn Sie eine bestimmte Situation schildern, beschreiben Sie Ihre Methoden der Problemlösung und die Maßnahmen, die Sie ergriffen haben. Verwenden Sie die STAR-Methode (Situation, Task, Action, Result), um ein klares Bild des Entwicklungsproblems und der von Ihnen durchgeführten Korrekturschritte zu vermitteln.
Question 3

Frage 3: Wie gehen Sie mit dem QA-Prozess um?

How to answer
So beantworten Sie die Frage: Qualitätssicherung ist ein wichtiger Aspekt der Softwareentwicklung und kann in kleineren Organisationen ohne designiertes QA-Team in den Aufgabenbereich der Entwickler fallen. Falls Ihnen eine Frage zum QA-Prozess gestellt wird, möchte die befragende Person ermitteln, ob Sie gewillt und in der Lage sind, als Teil der Rolle Testaufgaben und Bug Fixes zu übernehmen.

None of the above. 2 .Bob writes down a number between 1 and 1000. Mary must determine that number by asking "yes/no" questions of Bob. Mary knows that Bob always tells the truth.

(Zero or more answers may be correct.) A. word B. words C. c22 D. 42 E. None of the above. 6. If the variables below are properly initialized, and if i remains within array bounds, then the code below implements the stack operations Push and Pop. Note that the stack is held in an array S[1..N] indexed by the variable i. Push: begin S[i] := x; i :=i + 1 end Pop: begin i:=i - 1; x:= S[i] end Which of the following statements correctly initializes i for this implementation of a stack? A. i := N B. i := N-1 C. i := 1 D. i := 0 E. i := N/2 7. Consider a virtual memory with M resident pages and a page reference sequence p1, p2, . . ., pN of N distinct requests. Assume that physical memory is initially filled with unrelated pages, N = 2M, and a FIFO page replacement algorithm is used. If the access pattern is p1, p2, . . ., pN repeated three times, then the number of page faults is A. N/2 B. N C. N + 3 D. 2N E. 3N 8. Consider the following subroutine. int Func( int n ) { if( n == 4 ) return 2; else return 2 * Func( n + 1 ); } What value is returned by the subroutine call Func(2) ? A. 2 B. 4 C. 8 D. 16 E. 24 9. Consider a queue between the two processes indicated below. N is the capacity (maximum length) of the queue; e, f, and b are semaphores. "P" refers to the operation of acquiring (decrementing) a semaphore, and "V" refers to the operation of releasing (incrementing) a semaphore. init() { e = N; f = 0; b = 1; queue = EMPTY; } process1() { for(;;) { P(e); P(b); queue.enqueue(...); V(b); V(f); } } process2() { for(;;) { P(f); P(b); ... = queue.dequeue(); V(b); V(e); } } Which of the following statements is (are) true? (Zero or more may be correct.) A. The purpose of semaphore f is to ensure that dequeue is not executed on an empty queue. B. The purpose of semaphore e is to ensure that deadlock does not occur. C. The purpose of semaphore b is to provide mutual exclusion for queue operations. D. None of the above. 10. If V is a vector with n items and subroutine Exchange swaps its arguments, then the following code fragment sorts V in descending order. for( j = 0; j < n - 1; j++ ) for( k = 0; k < n - j - 1; k++ ) if( V[k] < V[k+1] ) Exchange( V[k], V[k+1] ); How many calls to Exchange are made if initially, V[i]=i, for i = 0, 1, 2, ..., n - 1 ?

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).
